摘要
为了分析台风过境前后周围观测站点气象要素的变化特征,文章利用上海海洋中心气象台所属站点及周边站点监测资料,对台风“米娜”过境前后气温、气压、2 min风速、相对湿度和能见度的响应进行分析。结果显示:小洋山国家基本气象站在台风影响下风速突增、气压明显下降、气温突降、相对湿度突降,台风影响结束后各气象要素变化至台风来临前水平,呈现出明显的台风过境特征;各站气压、相对湿度、能见度变化趋势基本相似;离海洋略远的定海国家基本气象站气温变化最剧烈,在海洋中的“fubiao1”和“fubiao2”气温变化最平缓;台风经过嵊泗国家基准气候站时,2 min风速随着台风“米娜”的靠近有所降低,表现出越靠近“台风眼”风速越小的特征。研究结果为台风天气下气象要素变化的研究提供参考。
In order to analyze the changes in meteorological elements at surrounding observation stations before and after the passage of Typhoon"Mina",monitoring data from the Shanghai Marine Center Meteorological Observatory and surrounding stations were used to analyze the response of temperature,pressure,2-minute wind speed,relative humidity,and visibility before and after the passage of Typhoon"Mina".The results showed that the Xiaoyangshan National Basic Meteorological Station experienced a sudden increase in wind speed,a significant decrease in air pressure,a sudden drop in temperature,and a sudden drop in relative humidity under the influence of typhoons.After the typhoon s impact ended,various meteorological elements changed to the level before the typhoon arrived,showing obvious characteristics of typhoon passage.The trend of air pressure,relative humidity,and visibility changes at each station is basically similar.The temperature changes at the Dinghai National Basic Meteorological Station,which is slightly away from the ocean,are the most severe,while the temperature changes at"fubiao 1"and"fubiao 2"in the ocean are the smoothest.When the typhoon passed through the Shengsi National Reference Climate Station,the 2-minute wind speed decreased as Typhoon"Mina"approached,showing a characteristic of decreasing wind speed as it approached the"eye of the typhoon".The research results provide reference for the study of meteorological element changes under typhoon weather.
