Abstract We have continued the interdisciplinary integration of the knowledge on climate and music and have developed the crosscutting study plans on the climate and cultural understanding education. A part of these results had been summarized in a Japanese book titled “Climate and music (Cultural understanding and ESD spreading from the “Doors of Song”)” (Kato and Kato 2019), building mainly our papers written in Japanese. This article will re-integrate our above study results, mainly for the climate and songs/traditional seasonal events around Germany, Northern Europe and Japan, with special attention to (A) asymmetric seasonal progression from autumn to next spring around Japan, (B) winter climate around Germany in association with the seasonal feeling on the traditional events “Fasnacht” for driving winter away and (C) climate around Northern Europe in association with the seasonal feeling on the summer solstice festival “Juhannus” with comparison to the summer climate around Japan.

Title Alternative For development of an ESD-based teacher training program on climate change : overlooking geo-phenomena on various timescales
FullText URL esr_027_001_017.pdf
Author Kato, Yuji| Kato, Kuranoshin|
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.

Title Alternative Synoptic climatological analyses of daily precipitation features and atmospheric fields in warm season relating to the precipitation difference between Kochi and Okayama characterizing the Seto Inland Sea Climate in Japan

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) .

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 This study is a part of the activity to develop an interdisciplinary lesson plan for high school students on the climate environment around Japan and the "seasonal feeling". This time, we focused our attention to the asymmetric seasonal march from autumn to the next spring as proposed by Kato et al. (2013). Comparison of the climate between early winter and early spring was made in the class not only on that around the Japan but also on the relation to the larger-scale systems such as the Siberian air mass, including the brief data analysis. The students also compared the detailed "seasonal feeling" between the two seasons expressed in the school songs and the Japanese classic poems called "Wa-Ka". This paper reports the contents and results of this joint activity at the two high schools.

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.
