【摘要】：本文利用2012年海南島19個常規(guī)氣象站、5個海島站的逐時資料以及�？谡镜奶娇召Y料,對海南島海風(fēng)的時空演變特征及在不同天氣條件下海風(fēng)發(fā)展的特征進(jìn)行了統(tǒng)計分析,結(jié)果表明:2012年全年海南島的海風(fēng)多發(fā)生于春、秋季,頻率分別為40%和33%,冬季最少(約為19%),尤其是一月,大部分站點(diǎn)均不足10%。夏季海風(fēng)出現(xiàn)時刻較早;南部沿海海風(fēng)結(jié)束時間晚于北部沿海;冬季海風(fēng)開始得較晚,南部海風(fēng)結(jié)束時間早于北部沿海。海風(fēng)平均持續(xù)時間約為10 h。沿海站的海風(fēng)風(fēng)速主要集中在3~6 m·s~(-1),且最大風(fēng)速值出現(xiàn)在春季,除瓊山、�？谡就�,最大海風(fēng)強(qiáng)度多出現(xiàn)于春夏季。內(nèi)陸站中部山區(qū)附近海風(fēng)出現(xiàn)頻率較高、開始時刻較早、持續(xù)時間較長、強(qiáng)度也較大。海風(fēng)向內(nèi)陸的傳播距離至少為70 km;海風(fēng)易發(fā)生在陰天,其次為多云天氣,少云日的海風(fēng)最少。
[Abstract]:Based on the hourly data of 19 conventional meteorological stations and 5 island stations in Hainan Island in 2012 and the sounding data of Haikou station, this paper makes a statistical analysis of the spatial and temporal evolution characteristics of the sea breeze in Hainan Island and the characteristics of the sea breeze development under different weather conditions. The results show that in the whole year of 2012, the sea winds in Hainan Island mostly occur in spring and autumn, with the frequency of 40% and 33% respectively, and the least in winter (about 19%, especially in January), most of the stations are less than 10%. The onset time of summer monsoon is earlier; the end time of southern coastal monsoon is later than that of northern coast; the winter monsoon begins later and the southern sea breeze ends earlier than that of northern coast. The mean duration of sea breeze is about 10 hours. The wind speed of coastal stations is mainly at 3 ~ 6 m ~ (-1) m ~ (-1), and the maximum wind speed appears in spring. Except Qiongshan and Haikou stations, the maximum wind intensity occurs in spring and summer. In the middle of the inland station, the sea wind appears more frequently, the beginning time is earlier, the lasting time is longer, and the intensity is larger. The distance from the sea breeze to the inland is at least 70 km; the sea wind is prone to overcast weather, followed by cloudy weather, with the least wind in less cloudy days.
