COMPARATIVE STUDY OF DIABATIC HEATING IN ANOMALOUS MEIYU YEARS
Abstract:In the context of ECMWF/WMO objectively analyzed gridded data,study is conducted of the features of atmospheric nonadiabatic heating fields in the years of plentiful and deficient Meiyu rainfall.Evidence suggests that such events bore an intimate relation to these fields;such fields showed different characteristics for different phase of the Meiyu;the fields were distinguished from each other as regards the features in the years of abundant and less Meiyu precipitation.
keywords:diabatic heating  Meiyu rainfall anomaly
