Outline of Research at the Start

降水量・風速、および1時間値気温データなどから、気象要素における種々の期間最大値の分布特性をもとめるべく極値分布を特定し、順序統計量として再現期間を推定する。その際、ベイズ統計を援用し、パラメタの分布特性そのものを推定したうえでモデルの評価を行い、これをもとに順序統計量を算出して再現期間を導出する。また、降水や風速、あるいは気温といった特定気象要素について、ベイズ統計を援用した最大値分布のモデル同定を目標とするだけでなく、各気象要素の同時生起確率も考慮した取り組みも併せて行う。

Outline of Final Research Achievements

In recent years, there have been many noticeable occurrences of river flooding, an increase in unseasonably hot summer days, and persistently hot summers, which are considered threats to the living environment. With strong suspicions of the onset of global warming, authors would like to clarify the extent of the risk to society. To this end, authors first estimated the return period of hourly precipitation, which could be an indicator of dangerous areas of precipitation that are the basis of urban planning, from the most recent AMeDAS weather data and performed a regional analysis. In addition, we assumed an occurrence probability model that preserves the dependency of these meteorological elements, and presented an improvement proposal for the building heat load design method as an example of extreme value design for temperature, solar radiation, and humidity.

Academic Significance and Societal Importance of the Research Achievements

温暖化の顕在化は、生活環境へのリスクを高めている。その代表が近年頻発している河川の氾濫であり、夏季の長期化と酷暑の高頻度化であろう。前者は降水量と密接に結びついており、都市計画においても、時間降水量の再現期間を指標としていることを考慮すれば、直近の再現期間を正しく見積もることには大きな社会的意義がある。また後者では、従来要素間の依存性を無視した極値解析が多いが、依存性を表現できる同時生起確率モデルを創出することで、正しい評価も可能になり、あらたな途を築ける。
