德阳市天气现象时空分布特征及农业影响分析
|
摘要
为了准确掌握德阳地区天气现象的时空分布特征,分析其对农业生产的影响,做好本地的精细化气象预报、准确发布预警信号,做好精准气象服务及天气现象自动化观测站点布局提供科学依据。利用Excel统计图表,对德阳所辖的什邡、绵竹、中江、广汉及德阳5个台站1981—2010年天气现象人工观测摘要后的25种天气现象进行统计分析。结果表明:德阳境内只监测到20种,年平均发生频率在50%以上的有轻雾、露、雨。雨凇、吹雪、龙卷、尘卷风及极光从未发生过。
The paper aims to accurately grasp the temporal and spatial distribution characteristics of weather phenomena in Deyang, analyze their impacts on agricultural production, conduct fine local meteorological forecast, issue accurately and early warning signals, promote precise meteorological services and provide a scientific basis for automatic weather observation station layout. By using Excel statistical charts, 25 kinds of weather phenomena were statistically analyzed after the summary of artificial observation of weather phenomena at 5 stations in Deyang from 1981 to 2010. The results showed that: only 20 phenomena were monitored in Deyang; the annual average frequency of light fog, dew and rain were more than 50%; the glaze,blowing snow, tornado, dust devil and aurora never happened.
