Typhoon Hagibis (2019) caused widespread flooding and damage over eastern Japan. The associated rainfall maxima were primarily observed on the windward mountain slopes along with the west of the leading edge of a low-level front. Concomitantly, a significant positive value in sea surface temperature anomalies (SSTAs) was observed in association with an ocean eddy over the Oyashio region, together with anomalous warmth over the entire western North Pacific. The present study examines the role of the SSTAs in the rainfall distribution associated with Hagibis, to deepen our understanding of the influence of the midlatitude ocean on tropical cyclones and associated rainfall. Our sensitivity experiments demonstrate that the observed warm SSTAs had the potential to displace the rainfall caused by Hagibis inland and thereby acted to increase precipitation along the Pacific coast of northeastern Japan. Our results suggest that midlatitude SSTAs on ocean-eddy scales can also influence the synoptic-scale atmospheric front and associated heavy rainfall.

The purpose of this paper is to show the process of how students construct their extracurricular music activities. Students at school play or listen to music not only in classrooms but also at after school club activities. Using ethnography as the method, this paper will focus on high school students in popular (band) music clubs and find out how they construct their music activities. The followings are the points that have been shown in this paper. 1) When students construct and maintain their music activities at a popular music club, two contexts operate, "self-achievement of music goals" and "achievement of human relationships". Music club activities can be classified into four sections from the crossing of these two axes. 2) "Achievement of human relationships" is the key to construct and maintain music activities. It was difficult to continue playing music when concentrating on one's self-achievement. In order to construct and maintain the music activity, it was essential for students to make good relationship with other members. 3) When constructing and maintaining music activity, girls attach importance to constructing human relationships whereas boys have strong need for achievement in playing music and becoming more skillful, Girls also tend to play music not only for improving their skills but use music as a way to build relationship with others. 4) The result suggests that group formation would be a major key for successful music activities in school music education. We should not ignore the fact that human relationship plays an important role when actually constructing and maintaining music activity. In other words, forming groups of individual acting separately would not work. Group formation should be based on each individual's meaningful choice and each individual should be able to attach meaning to the group itself. Successful human relationship is the key for construction and maintaining music activities.

Rapid understanding of the magnitude of large earthquakes and their associated fault dimensions are extremely important. Since September 2012, Geospatial Information Authority of Japan (GSI) and Tohoku University are jointly developing the GEONET real-time analysis system (REGARD). REGARD system rapidly estimates two types of coseismic fault models, which are slip distribution along the plate interface and single rectangular fault model, using permanent displacement field based on the real-time GNSS tine series. Currently, REGARD adopted the maximum likelihood approach to estimate the optimum model. The system has two points to be improved. As first point, it is difficult to estimate the quantitative uncertainty estimation of the obtained result because of the estimated result should contain both of the observation error of the real time GNSS and modeling error caused by the model settings. Understanding of such uncertainties quantitatively based on the data is important for evaluation of the result for disaster response. Second point, the problem is non-linear to estimate the single rectangular fault model in REGARD. Thus, the result strongly may depend on the initial values of the fault parameters. It is necessary to find the global minimum quickly for real-time use.Based on these backgrounds, we are developing coseismic fault model estimation system using MCMC (Markov Chain Monte Carlo methods), which is probabilistic approach based on Bayesian statistics. MCMC does not specify one maximum likelihood value, but estimates the posterior probability density function (PDF). In addition, dependency on the initial value is relatively small by searching unknown parameters over a wide range randomly. In this study, we focus on the development the algorithm to estimate the single rectangular fault model deduced from permanent coseismic displacement field in real-time. We adopted basic Metropolis Hasting method as sampler and utilized parallel tempering approach to improve the sampling efficiency. One of the challenges for using MCMC in real time is how to make search settings, such as initial value, walk distance, variance of likelihood function, and Burn-in, which are generally decided by the try and error. We suggest a method of deciding these values automatically using scaling law and original sampling flow. Other challenging issue is calculation time. In generally, the calculation cost of MCMC is problem for the real-time purpose. To improve the performance of the MCMC we adopted OpenMP for the parallelization of the computing.We applied this approach to the 2011 Tohoku-Oki earthquake, 2016 Kumamoto earthquake, and 2016 Fukushima-Oki earthquake using the actual permanent displacement time series from REGARD. In each estimations, we got 1×106 samples and obtained posterior PDF within 30 seconds. To emphasize, this algorithm could estimate the magnitude as distributions based on the data. Especially in Tohoku-Oki earthquake, obtained results clearly shows the tradeoff between the fault area and the slip amount. This result suggests that the onshore GNSS data cannot constrain them, which are extremely important factors for precise near-field tsunami forecasting.In our presentation, we will show the more detail characteristic of the algorithm. We are working on development of it for single rectangular fault model aiming at actual operation. Furthermore, we will expand this approach to not only the single rectangular fault but also the slip distribution along the plate interface.

「扇絵」は扇にするために扇面に描かれた絵である。しかし扇はその形態ゆえに傷みやすく、経年劣化した過去の扇は、保存修復の為、しばしば扇骨を抜かれ平らに表装されている。そしてそれらの扇絵が調査される際は、その平面になった状態のままで研究が続けられている。しかし扇絵を正しく解釈するには、元の姿を推定することが重要と考え、ここで元の扇を復元的に制作したものを「再現扇」と呼び、「扇絵」の理解の為の手段として提案した。 「再現扇」の制作には、推定が必要であり、1.折面と扇骨の位置関係、2.折目線と折面の状態、3.扇面比に伴う歪みの変化、などの扇そのものの物的・工作的特性と、4.扇絵自体の描画特性、の4項目を手掛かりとした。またそれらに加え過去の扇の計測数値や、江戸時代の絵師が描いた現存する扇の描画例も推定の参考にした。 次に先行研究から、「写楽扇面」の調査分析、及び「源氏物語絵扇面」の構図分析の二事例を取り上げた。それらに対し、具体的に「再現扇」を作成することによって従来とは異なる観点からの解釈を行った。 結果、①写楽扇面は、折目の存在からそれぞれ異なる履歴を想定した二説があったが、再現扇の作成を通じて新たな履歴が想定された。そしてその立体となった扇からは平面とは異なり登場人物の視線が自然と向き合う動きのある歌舞伎の一場面を感じさせるものとなった。また調査対象となった、同じく写楽作とされる「老人図」の扇とも類似する扇の形態を妥当と考えるに至った。②源氏物語絵扇面は室町時代の作である。扇絵に描かれた不自然に見える柱や床の歪みを矩形に変換することで構図解明が追求されてきたが、矩形の再現図では歪みは解消できていなかった。それに対し「再現扇」からは「歪み」の不自然さは感じられず、凹凸を生かした奥行きのある構図となった。源氏絵を得意とした土佐派は、当時より、扇絵の描画特性を備えた固有の描画法を確立していたのではないかと考えさせる結果となった。

This brief essay is a case study of a young Japanese man’s intercultural experience between 1870-73. Kenzo Hirosawa, an adopted son of the prominent Chōshū politician Saneomi Hirosawa, had a rare opportunity of living with the US consul in Tokyo for almost a year before leaving for New York to study. Articles written about Kenzo and his uncatalogued papers illustrate the vivid and often turbulent aspects of international education in early Meiji period.

In early July 2020, an extreme rainfall event generated precipitation exceeding 1000 mm in Kyushu district, southwestern Japan. Especially, an elongated and stagnated mesoscale convective system formed around the Kuma River in central Kyushu district produced localized heavy rainfall with precipitation over 600 mm in 13 hours. Characteristics of this extreme rainfall event were investigated using distributions of radar/raingauge-analyzed precipitation amounts (RAP) that were statistically compared with those during the warm seasons (April–November) in 2009-2019. The results are as follows: (1) nine heavy rainfall areas of linear-stationary type (LS-HRAs) were extracted, (2) spatial and temporal scales of two LS-HRAs among the nine exceeded 270 km and 10 hours, respectively, (3) the maximum RAP exceeding 100 mm in LS-HRAs were comparable to those in previous extreme rainfall events, (4) large accumulated three-hour precipitation amounts exceeding 200 mm were more frequently observed than those in previous events, and (5) the accumulated five-day precipitation amount integrated around Kyushu Island was the largest since 2009. This study also showed that a large area-integrated precipitation amount was produced mainly from widespread precipitation systems associated with the Baiu front, while the nine LS-HRAs significantly contributed to localized heavy rainfall.

Aerosol effects on deep convective cloud (DCC) have been recognized as one of the complex subjects in climatic studies because of the difficulty in quantifying the sole effect of aerosols on DCC. The complexity further arises if the atmosphere has very strong temporal and spatial variations such as that of Indo-Pacific Warm Pool (IPWP) region. Considering the strong influence of IPWP region on global climate change and water circulation, we investigated aerosol effects on DCC over this region by using data of 2015-2016 El Niño and the 2017-2018 La Niña events. We developed a spectral analysis based framework to identify and decouple the influences of major external factors on aerosol-DCC relationship. We found that temporal variations of aerosols, clouds, and meteorology longer than 2 days' time scale can have larger influences than their diurnal and spatial variations on aerosol-DCC relationship. By removing the effects of those spatial and temporal variations of different scales, the study suggests that aerosols of IPWP region can affect DCC properties with time lags less than ∼5 hours and by increasing cloud-top height, cloud coverage, and DCC number concentration with the increase of aerosols.

The present study was conducted to examine alterations in the concentrations of plasma free amino acids, glucose, insulin, free fatty acids (FFAs), and urea nitrogen induced by branched-chain amino acid (BCAA) supplementation in young men. Overnight-fasted subjects ingested drinks containing 1 or 5 g of a BCAA mixture (weight ratio of 1 : 2.3 : 1.2 for isoleucine : leucine : valine), and blood was intermittently collected for 3 h after ingestion. Ingestion of the BCAA mixture resulted in significant increases in the plasma concentrations of individual BCAAs, corresponding to the amounts of amino acids ingested. On the other hand, plasma concentrations of methionine and aromatic amino acids tended to decrease in the trial with 5 g BCAAs, suggesting that BCAA ingestion affects the metabolism of these amino acids. The ingestion of BCAAs temporarily increased plasma insulin levels and affected plasma concentrations of FFAs, but had almost no effect on glucose or urea nitrogen.
