- Quantitative Evaluation of the Predictability of Tornado and Gust Phenomena by Cutoff Low
Honda Akiharu
The cutoff low is a cold air system in the upper troposphere that often accompanies extreme weather events such as tornadoes and wind gusts that cause disasters. The cutoff-low (COL) index, which objectively evaluates the location of the center, intensity, and radius of influence of the cutoff low, has been developed to improve the lead time for predicting extreme weather events associated with cold extremes. The COL index is available as the COL Map on the "Cutoff Low Tracking and Monitoring System," a website for monitoring cold air behaviors in the upper troposphere at Niigata University., Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research, 2017/04 -2021/03, Grant-in-Aid for Scientific Research (B), Niigata University - Local circulations developing in Keihanna area in warm seasons
YAMANE Shozo
In the Keihanna area and the surrounding region on sunny days in warm seasons, the convective mixed layer develops vigorously after the sunrise, and the winds in the direction similar to those in the upper layer begin to blow near the ground around 10am. The sea breeze from Osaka bay also forms near the coast after the sunrise and progresses inland during the daytime. The local mountain winds blow at night in the vicinity of the slopes of the mountains and valleys, and the wind direction reverses within several hours from the sunrise. The surface winds in the Keihanna area on the evening of the sunny days in warm seasons were classified into four types: weak wind type, eastward wind type, westward wind type, and southward wind type. On the sea breeze days, which were classified into the eastward wind type, the time of daily maximum temperature and the time of daily maximum photochemical oxidant concentration tend to be faster than the times on the weak wind days in the Keihanna area., Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research, 2015/04 -2018/03, Grant-in-Aid for Scientific Research (C), Doshisha University - Comprehensive Study of the Formation and Variability of the Tropo-spheric Circulation by Utilizing Latest Reanalysis Dataset

Through analysis of the new reanalysis data of the global atmosphere (JRA-25) and numerical modeling, (1) we have postulated a new framework of the atmospheric general circulation with particular emphasis on the role of interaction with midlatitude oceanic frontal zones in the formation of westerly jet and its dominant variability, (2) revealed the characteristics of two anomaly patterns as a dynamical mode that influence of the summertime Bonin High, (3) elucidated the dynamics of the Southern Hemisphere summertime subtropical highs, and (4) assessed the pre-dictability of the tropospherestratosphere coupled variability., Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research, 2006 -2009, Grant-in-Aid for Scientific Research (A), The University of Tokyo - Hierarchical unstable structures in atmospheric general circulation

地球を取り巻く大気の運動は不規則であり、様々な時間・空間スケールの現象が存在する。このような大気場の中で発達する微小な擾乱の地理的分布・空間構造の特徴を大気大循環モデルの数値実験を通して調べた結果、擾乱のエネルギーが比較的小さいときは熱帯の対流活動に伴う擾乱の発達が顕著となり、擾乱のエネルギーが比較的大きいときは中緯度帯の移動性高・低気圧に伴う擾乱の発達が顕著となる傾向があることが分かった。, Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research, 2007 -2008, Grant-in-Aid for Young Scientists (B) - Research on the formation mechanism of the Cold Ocean-Warm Land pattern

The Arctic Oscillation draws increasingly more attention in recent years in association with abnormal weather and global change problems. In the first year of 2006, the first workshop on the Arctic Oscillation Study was held during 7-8 July 2006 at the University of Tsukuba. About 30 participants gathered to present the latest scientific results and to discuss on the subject. The head investigator organized the 7th International Conference of the Global Change: Connection to the Arctic (GCCA-7) at the University of Alaska Fairbanks for 19-20 February 2007 and presented the review of the Arctic Oscillation study. The second workshop on the Arctic Oscillation Study was held during 2-3 March 2007 at the University of Tsukuba. About 40 participants gathered to present the latest scientific results and to discuss on the subject. In the second year of 2007, the bead investigator organized the first union session of the Sciences in the Arctic during the Japan Geosciences Union Meeting 2007 with a special topic of the Arctic Oscillation. The union session is upgraded to the regular session in 2008. The contributions from the Arctic Oscillation Studies were summarized as the Special Edition of the Journal of the Meteorological Society of Japan in December 2007 issue. In the Special Edition, 12 refereed papers on the subject of the Arctic Oscillation were published. According to the summary of these papers, we have reached to the conclusion that the Arctic Oscillation can be understood as a dynamical singular eigenmode of the global atmosphere. The singular eigenmode has a unique property of zero eigenvalue with a structure identical to the Arctic Oscillation so that it can respond resonantly to arbitrary quasi-steady barotropic forcing. However, the quasi-steady forcing from the storm tracks at the Pacific and Atlantic sectors acts independently with large amplitudes, so the Arctic Oscillation apperas as if it is a statistical artifact of the EOF analysis, recognizing only the teleconnections of NAO in the Atlantic sector and PNA in the Pacific sector., Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research, 2006 -2007, Grant-in-Aid for Scientific Research (A), University of Tsukuba - The Role of Midlatitude and Subtropical Air-Sea Interactions in the Formation and Variability of the Atmospheric Circulation Systems

・Unlike in other mid-latitude oceanic regions, anomalous surface heat flux in the North Pacific sub-arctic frontal zone is controlled by local sea-surface temperature (SST) anomalies associated with its inherent decadal variability. This oceanic thermal forcing accompanies meridional shift of the storm track. Our GPS-sonde observations have revealed that the frontal SST distribution accompanies spatial imhomogeneities in static stability and thereby downward momentum transport in the boundary layer, leading to positive correlation between SST and surface wind speed. ・In the Southern Hemisphere, the storm0track core is anchored throughout the year along the surface baroclinic zone associated with the major oceanic frontal zone in the Indian Ocean, where a polar-front jet (PFJ) with surface westerlies forms due to poleward eddy heat transport. We are the first to point out a possible dynamical association among a storm-track, PFJ and oceanic frontal zone. Over the South Pacific, the association is disturbed in winter when upper-level eddies are trapped into an intensified subtropical jet (STJ), below which surface baroclinicity. Our new concept can provide a plausible interpretation for the seasonal march in the North Pacific storm-track. ・We have revealed that the surface Okhotsk High forms in response to cold advection by anomalous low-level easterlies induced by an upper-level blocking high to its northwest, which amplifies due to local breaking of an Rossby wave-train propagating from northern Europe. ・As opposed to the previous understanding, we have revealed that the summertime subtropical anticyclones form in response to the profound thermal contrast between the cool eastern ocean and the warm, dry continent to its east. ・To the south of Australia, where a PFJ overlaps with the stratospheric polar-night jet, a vertical waveguide forms through which stationary Rossby wave-trains propagate from the lower stratosphere downward to generate localized anomalous circulation in the troposphere., Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research, 2003 -2005, Grant-in-Aid for Scientific Research (B), The University of Tokyo
