| Abstract | Since the recent climate change is an important topic in the context of SDGs (Sustainable Development Goals) and ESD (Education for Sustainable Development), teacher training course should produce educators with sufficient geo-literacy. In order to meet this requirement, the authors have designed a study plan that facilitates students’ better understanding of current climate change issues, which will be offered in a lecture at university by two speakers who have different specialties, paleoenvironmental science and meteorology. Summary of the lecture is as follows. At first, from the branch of paleoenvironmental science, a major cooling event at the Eocene/Oligocene boundary and the glacial-interglacial cycles in the Quaternary will be explained. We will then instruct the participants to compare these climatic events with recent global warming, in order to remind them of the extraordinary higher speed of the recent climate change than climatic events in the geological past. Followed by these global topics, climatological features in East Asia including Japan (e.g. regional/seasonal difference in climate and year-to-year variations) will be demonstrated in order to relate local issues to global ones. By these efforts, the lecture aims to cultivate students’ ability to grasp geophenomena from various aspects and understand the true nature of problems, which may contribute producing educators who can execute ESD programs. |

| Abstract | In order to re-examine the formation process of the climatological precipitation difference between Kochi (Pacific side of Shikoku District) and Okayama (Seto Inland Sea side) characterizing the Seto Island Sea Climate in warm season, synoptic climatological analyses of the daily precipitation features and atmospheric fields were performed for the warm season (April to September) of 1985 - 2015, based on the daily and hourly precipitation data and weather maps by the Japan Meteorological Agency (JMA), and the NCEP/NCAR re-analysis data. The large climatological difference of precipitation at Kochi from that at Okayama throughout the warm season was greatly contributed to by the days with the precipitation difference between Kochi and Okayama (ΔPR) with greater equal to 30 mm/day. In addition, such large daily ΔPR was mainly due to the intense rainfall at Kochi with greater equal to 10mm/h throughout the warm season, except for a part of the cases in April when the “not so intense rain” with less than 10mm/h at Kochi contributed to the large ΔPR. However, it is noted that the features of the synoptic-scale atmospheric fields and possible roles of the mountain ranges in Shikoku District causing the large ΔPR were rather different among August (midsummer), September (Autumn rainfall season) and April (Spring) . |

| Title Alternative | Interdisciplinary ESD lesson study for the university students with attention to the difference of climate and seasonal feeling in “summer” among Germany, northern Europe and Japan |

| Abstract | Climatological features and seasonal feeling in the season called by the same word such as “summer”would be rather different from region to region. Comparison of these features among the different regions, including the regions which are not so familiar to the students, would help to promote their fundamental ESD literacy, especially relating to the “Understanding of heterogeneous others”. Based on that concept, this paper will report an interdisciplinary lesson study for the university students on a theme how different the summertime climate and seasonal feeling among Germany, northern Europe and Japan are. In this study, the lesson practice was made in 2015 and 2018. In both classes, after the lecture on the summertime climate and seasonal feeling in these regions, the students created substitute songs with use of the melody of “Alles neu macht der Mai” (“The May makes all things new”, the same melody as a Japanese school song “Butterfly”) for the comparison between Germany and Japan. As for that between northern Europe, the melody of a Japanese school song “Furu-Sato” (“My country home”) was used for the creation of the substitute songs. It is noted that, not only the seasonal mean temperature or solar radiation condition, but also the features in association with the large day-to-day temperature variation was strongly reflected in the students’ works. |

| Abstract | An interdisciplinary study plan on the seasonal transition from autumn to winter around the Japan Islands and the “seasonal feeling” associated with the shallow convective rainfall “Shi-gu-re” in that stage expressed in the Japanese classic poems called “Wa-ka” was developed, through a lesson study at junior high school. In that study plan, special attention was paid to the seasonal evolution of the larger-scale systems from autumn to winter, such as the Siberian air mass and the Siberian high, and the relation to the cold air intrusion into the Japan Sea and the Japan Islands. According to the analysis of the lesson practice results, students seem to understand that the winter-type weather pattern becomes dominant around November, together with the features of the intermittent rainfall in the winter-type pressure pattern called “Shi-gu-re” expressed in the “Wa-ka”. However, necessity of further improvement of the study plan was pointed out, so that the students can understand more exactly the role of the seasonal development of the Siberian high and Siberian air mass in the climate around the Japan Islands. |

| Abstract | Synoptic climatological analyses associated with the large day-to-day variation of air temperature around Germany in winter were performed based mainly on the NCEP/NCAR reanalysis data for 2000/2001 to 2010/2011 winters, with an interest in the relationship to the “seasonal feeling” in “Fasnacht”, the festival for driving the winter away. The intermittent appearance of the extremely cold days with rather large day-to-day variation in winter as pointed out by Kato et al. (2017) for around Germany was seen also to the north and to the east of Germany. According to a case study for the 2000/2001 winter, such large daily mean temperature fluctuation was closely related to the intraseasonal variation of the Icelandic low with about one month period, i.e., while the temperature around Germany was relatively higher at the eastward shift phase of the Icelandic low due to the strong warm air advection by the SW-ly wind, the temperature was extremely low there when the Icelandic low was weakened and retreated westward. |

| Abstract | Although the extratropical cyclone is one of the basic systems that characterize the weather and climate in mid-latitude regions with the large meridional temperature gradient, its activity and characteristics would be greatly influenced by the seasonal transition and regional differences of the mean atmospheric fields such as between Europe and East Asia. Furthermore, detailed knowledge of the daily cyclone activity would help to understand deeply the differences of regional climatology including seasonal cycles among various areas. In such interest, the present study performed a case study on the cyclone activity around Europe from winter to spring of 2000. In winter, intraseasonal variation of the Icelandic Low was dominant. In the stage when such intraseasonal-scale Icelandic Low approached to the northwestern Europe, the several lows passed eastward with a few days interval around the intraseasonal-scale low pressure area or its southern edge where the baroclinicity was relatively strong. It is also noted that their center pressure was rather low (below 980hPa). After April, when the seasonal mean Icelandic low had disappeared, different types of the intra-seasonal-scale cyclones and anticyclones were dominantly observed. In the lower SLP stage of the intraseasonal variation in Europe, the low to the southwest of England in the middle of April was of the equivalent barotropic structure and persisted for about ten days. On the other hand, high pressure area extending from England to the northern coast of Germany also persisted for about half month. The southern half of that high area was also of equivalent barotropic structure with warmer air there. |

| Abstract | Around April, total precipitation in southern Kyushu already attains rather large value due to the increase in contribution of the “heavy rainfall days” (with daily precipitation more the 50 mm/day, referred to as HRD). The present study examined the rainfall features and atmospheric conditions on the HRDs at Kagoshima in southern Kyushu, based on the operational observation data from 1990 to 2009. The HRDs there in April appeared mainly associated with the extratropical cyclone passage, together with tentative appearance of the stationary front. The mean daily precipitation on the HRDs was 82 mm and contribution of the intense rainfall more than 10 mm/h attained up to 38 mm, which accounted for 46 % of the daily total precipitation. In April, the high specific humidity area in the time mean field was still located far to the south of the Japan Islands and the stratification around the Japan Islands was very stable for deep moist convection. However, the zone with rather strong seasonal mean baroclinicity extended to rather southern area near 20°N. This would provide a favorable condition for the long-distance moistur |

| Abstract | Rainfall characteristics and large-scale atmospheric fields on the “heavy rainfall days” (with more than 50mm/day) in midsummer, and so on, at Tokyo in the eastern Japan were examined for 1971 to 2010, succeeding to Matsumoto et al. (2013) The present study firstly examined the rainfall features and the atmospheric fields for the “heavy rainfall days” at Tokyo with rather lower appearance frequency than in the typhoon related patterns in Matsumoto et al. (2013) and so on. In these cases (three cases in total), although the synoptic situations were rather different among each other, they seem to occur under the systems with relatively small zonal scale associated with the great meander of the upper-level westerly wind. Next, the climatological analyses similar to Matsumoto et al. (2013) were performed for the "heavy rain days" at Tokyo in midsummer (1~31 August). The precipitation on the “heavy rainfall days” at Tokyo in midsummer was mainly brought by the intense rainfall with more than 10 mm/h, as in the western Japan in the mature stage of the Baiu season. The detailed examination of the rainfall features for the case on 10 August 2009, with use of the 10-minutes precipitation data and the Radar AMeDAS Composite Data by the JMA, revealed that the organized meso-β-scale convective rainfall systems as often appear in the western Japan in the mature stage of the Baiu season were just to the east of the typhoon, and brought the intense rainfall at Tokyo to result in the large daily precipitation. |

| Abstract | Preliminary analyses on the seasonal cycles of the large-scale atmospheric mean fields and the cyclone activity in Europe were performed based mainly on the NCEP/NCAR re-analysis data, at the viewpoint comparing with those in East Asia. As for the climatological monthly mean fields (1981~2010), the meridional temperature gradient in East Asia presents striking seasonal change with the maximum in winter and the minimum in summer. It is interesting that such transition from winter to summer and that from summer to winter occur rather rapidly accompanied by the great temperature increase around April to June and the decrease around October to November, respectively, in a wide region of 40~70N. On the other hand, the temperature gradient in Europe is significantly smaller with slight seasonal change than that in East Asian winter. By the way, in spite of the above difference of the horizontal temperature gradient between Europe and East Asia, the cyclone activity does not seem to be so weak even around Europe. Thus, the seasonal cycles of the characteristics of the cyclones and their environmental fields around Europe were examined. At the first step, we analyzed the daily cyclone activity in Europe for January and July of 2000. Many low pressure centers at the surface level appeared in both January and July. Referring also to the daily maps of sea level pressure and geopotential height at 500 hPa level, we found that not only the cyclones corresponding to the baroclinic instability waves, but also to the cold vortices which amplitudes increased with height appeared frequently. Moreover, it is interesting that the large-scale cold vortex, which embeds the shortwave trough with the low center at the surface level, appeared in the northern Europe in July as in East Asian winter, when such multi-scale systems sometimes bring the persisting heavy snowfall events in the Japan Sea side of the Japan Islands. |

| Abstract | Rainfall characteristics and large-scale atmospheric fields on the “heavy rainfall days” (with more than 50 mm/day) in the mature stage of the Baiu season (16 June ~ 15 July) at Tokyo in the eastern part of the Japan Islands were examined, based on the daily and the hourly precipitation data from 1971 to 2010. Appearance frequency of the “heavy rainfall days” at Tokyo attained only about 1/3 of that at Nagasaki in the western Japan. Furthermore, it is noted that about half of the “heavy rainfall days” at Tokyo were related to the typhoon. In detail, about half of the typhoon cases were associated with the direct approach of a typhoon (referred to as Pattern A, hereafter), the other half corresponded to the situation when the Baiu front also stagnated around Kanto District with a typhoon to the southwest of Kanto (Pattern B). Although the contribution of the intense rainfall with more than 10 mm/h to the total precipitation was large in Pattern A, that with less than 10 mm/h was dominant in Patterns B and C (Pattern C: meso-α-scale cyclone on the Baiu front approaching to the Kanto District). It is noted that about half of the “heavy rainfall days” corresponded to these pattern. In other words, unlike the localized torrential rain in western Japan, the “heavy rainfall days” due to the duration of “not-so-intense-rain” appeared rather frequently in the eastern part of Japan even in the Baiu season. In both Patterns B and C, relatively strong low-level southerly wind associated with the disturbance (a typhoon or a meso-α-scale cyclone) invades into the baroclinic zone in the basic field sustained as the sowthwestern edge of the cool Okhotsk air mass. It is interesting that the “heavy rainfall days” there due to the contribution of the persistent “not-so-intense-rain” occur just in such situation. |

| Title Alternative | A case study on the rainfall distribution over the Japan Islands associated with the approach of Ty0423 in late October (Comparison with that for Ty0418) |

| Abstract | Rainfall distribution in the Japan Islands associated with the approach of Typhoon No.23 around 20 October 2004 (referred to Ty0423, hereafter) showed considerably different features from those in late summer of this year. The present study examined the detailed rainfall features around the Japan Islands brought by Ty0423 and the atmospheric processes based on the operational observation data by the Japan Meteorological Agency (JMA), comparing with those in association with Ty0418 around 7 September 2004. During the stage when Ty0423 was approaching or landing on the western part of the Japan Islands, the areal mean precipitation from Kyushu to Kanto District attained much larger than that for Ty0418, with wider extension of the area with the large amount of precipitation. It is interesting that, although the intense rainfall was observed only at the upstream side of the mountain range from Kyushu to Honshu District for Ty0418 except for the area near its center, strong rainfall with 10~30 mm/h persisted in wider regions from the western to the eastern part of the Japan Islands, resulting in the considerably large total rainfall for Ty0423. As for the case for Ty0423, the surface front with stable frontal surface was located just to the east of the Ty0423 center just before its landing at the Japan Islands. Thus, the huge moisture inflow mainly in the eastern region from the typhoon center seems to be redistributed widely over the Japan Islands area associated with the large-scale convergence around the stable frontal surface. In late October, the colder air associated with the high pressure system in the eastern Siberia can cover the northern part of the Japan Sea area as the seasonal march. Such basic field might be favorable for sustaining the synoptic-scale front just around the southern coast of the Japan Islands, even when the strong southerly wind invades associated with the typhoon approach there. |

| Abstract | 梅雨は，アジアモンスーンの影響を顕著に受けた現象の一つである。本研究では，豪雨の起こり方に注目した日降水量データの分析活動や気象衛星画像の観察など通して梅雨について学ぶ学習プランを開発した。これは中学校理科での「日本の四季の天気」に関する探究的要素も含めた授業提案であるが，高等学校の『地学基礎』，『地学』，『地理』における活用も視野に置いた。研究科教員による附属学校園への相互乗り入れ授業の一環として，岡山大学附属中学校1年生を対象に授業実践を行い，結果について検討した。西日本では，東日本と違い，『大雨日』が頻繁に出現することを反映して，気候学的に総降水量が大変多くなる。授業では，そのような特徴の一端を九州の長崎と関東の東京の6〜7月における1971〜1998 年の日降水量の表から読み解く作業・考察を，中心的活動の一つに据えた。 |

| Abstract | A case study on persistent appearance of the ensemble of precipitation bands in the warm sector of the Baiu front in Kyushu District, the western part of Japan around 19 June 2001 was performed based on the operational observational data. Around 00UTC (09JST) 19 June when the Baiu front on the surface weather map was still located about a few 100kms to the north of Kyushu, the number and the total area of the meso-β or γ-scale line-shaped precipitation bands increased around Kyushu rapidly. These precipitation bands had been sustained there and gradually gathered each other to change into the Baiu frontal precipitation zone extending from the northern Kyushu to Seto-Naikai (Seto Inland Sea) around 09UTC (18JST) 19 June (the intense rainfall zone was still located in the warm sector of the Baiu front). Until ~09UTC (18JST) 19 June, the moist air flow with the latently unstable stratification had been sustained around Kyushu corresponding to the low-level southerly wind toward the surface Baiu front to the north of Kyushu. This large-scale situation would contribute greatly to the maintenance of the ensemble of the line-shaped precipitation bands in the warm sector of the Baiu front. |
