未来24 h预报是每个气象台的日常工作内容,随着人们对天气预报的关注日益增加,对乡镇温度预报准确率提出了更高的要求。本文结合抚顺地区87个自动气象观测站的数据及位置分布,选取一个数据最为完整的观测站作为代表站,绘制全市各观测站与本站的逐月温差图,研究全市气温分布规律,在此基础上以新宾县15个乡镇为例提出了等差值乡镇温度预报订正方法并对结果进行检验。结果表明:抚顺地区全年温度分布趋势具有明显的季节性变化;用等差值乡镇温度预报订正方法对新宾县15个乡镇进行温度预报,发现温度准确率大部分在80%以上。
未來24 h預報是每箇氣象檯的日常工作內容,隨著人們對天氣預報的關註日益增加,對鄉鎮溫度預報準確率提齣瞭更高的要求。本文結閤撫順地區87箇自動氣象觀測站的數據及位置分佈,選取一箇數據最為完整的觀測站作為代錶站,繪製全市各觀測站與本站的逐月溫差圖,研究全市氣溫分佈規律,在此基礎上以新賓縣15箇鄉鎮為例提齣瞭等差值鄉鎮溫度預報訂正方法併對結果進行檢驗。結果錶明:撫順地區全年溫度分佈趨勢具有明顯的季節性變化;用等差值鄉鎮溫度預報訂正方法對新賓縣15箇鄉鎮進行溫度預報,髮現溫度準確率大部分在80%以上。

Forecast of the next 24 hours is the daily work content of each meteorological station. As people pay more attention to the weather forecast,the higher temperature forecast accuracy of villages and towns are required. In connection with the distribution of the data and the location of 87 automatic weather stations in Fushun City,one observation station with most complete data was selected as a representative station,monthly temperature difference chart was drawn,and the temperature distribution of the city was studied. On this basis,taking 15 towns in Xinbin County for example,a methodology of temperature forecast correction method was proposed to test the results. The results showed that: Annual temperature distribution trend of Fushun area has obvious seasonal variation;Using the methodology to correct the values of the temperature forecast of 15 towns in Xinbin County,the accuracy of the temperature mostly are above 80%.
