| 摘 要： | 利用四川省145个气象台站1981～2013年连续人工观测资料，对34种天气现象发生日数和概率进行统计。结果表明:除极光外，四川省共观测到33种天气现象，露和轻雾日平均发生频率大于40%；雨和阵雨日平均发生频率大于20%；结冰、霜和雷暴日平均发生频率大于10%。露、霜、结冰、雷暴、闪电、大风、积雪、雨、阵雨、雨夹雪、雪11种天气全省各站均有发生，而雨凇、雪暴、吹雪、龙卷仅在个别站点发生。液态降水、雾、轻雾、霾、浮尘、烟幕、露均是盆地内多于高原，而混合降水、固态降水、扬沙、沙尘暴、吹雪、雪暴、雷暴、霜、大风、结冰、积雪、冰针、龙卷、尘卷风则是川西高原多于盆地。

| Abstract: | Base on the continuous and artificial observation records of 145 meteorological stations in Sichuan Province during 1981-2013, the days and frequency of 34 kinds of weather phenomena occurrences were analyzed. The results showed that the other 33 kinds of weather phenomena except aurora were observed. The daily frequency of dew and mist was more than 40% while rain and shower was more than 20% and icing, frost and thunderstorm was more than 10%. 11 kinds of weather phenomena including dew, frost, icing, thunderstorm, lightning, gale, snow cover, rain, showery rain, sleet and snow were observed in the stations all around Sichuan but these kinds about glaze, snowstorm, blowing snow and tornado observed only in a few sites. The basin's occurrence frequency of liquid precipitation, fog, mist, haze, floating dust, smoke and dew were more than Western Plateau while the mixed precipitation, solid precipitation, sand, dust storm, snow blowing, snowstorm, thunderstorm, frost, gale, icing, snow cover, ice needle, tornado and dust devil were just the opposite. |
