| Abstract: | Based on the observation data of surface temperature,wind,relative humidity and solar radiation of Yulin station in recent 50 years(1961-2010),the historical weather maps and NCEP/NCAR reanalysis data,the climatic characteristics of high temperature summer weather were statistically analyzed and its general circulation features are discussed.The results showes that 1) the hot days usually occurred in June to September and the cases,which last at least 3 hot days,mainly happened in July to August.The days of hot varied greatly between years.There are small daily mean wind speed,high daily mean relative humidity and temperature,as well as greater monthly mean sunlight hours during hot weather process.2) There are three types of large-scale circulation,which would cause the hot weather: the subtropical high controlling type,tropical cyclone periphery type and the subtropical high coinciding with tropical cyclone type.The lasting time of high temperature weather was closely related to the intensity of subtropical high.While the subtropical high was strong,expanded more wests and covered the South China,there were usually appearing the hot weather;when the downward flow of tropical cyclone affected Yulin,the extreme heat days often happened;when the subtropical high affected Yulin associated with the tropical cyclone,the heat days persist and the temperature would be higher. |
