摘要
阐述了旅顺口区北海、铁山、水师营3个站的最低温度、最高温度相较于旅顺站的差异特征,提出了3个站的温度修正度数,介绍了3个街道温度变化气候因素。结果表明,乡镇自动气象站与旅顺站之间的最低温度、最高温度有明显差异,全年各乡镇的最高温度均比旅顺站偏高,而最低温度均低于旅顺站,而且这种差异随着季节的变化而不同。部分乡镇观测环境不标准,温度变化起伏较大,可能是造成乡镇预报准确率偏低的原因之一。随着观测环境的改善和旅顺站温度预报质量的提高,利用该方法制作的乡镇温度预报准确率也将随之提高。
The differences between the minimum,maximum temperature of 3 stations in Beihai,Tieshan and Shuishiying of Lvshunkou District and Lvshun Station were described.The temperature correction degree of 3 stations was presented,and the climate change factors of 3 streets were introduced.The results showed that there was an obvious difference between the minimum temperature, the maximum temperature between the township automatic weather stations and Lvshun Station, the maximum temperature of all townships and towns in this year was higher than that of Lvshun Station, and the minimum temperatures was lower than that of Lvshun Station ,which varied with the season.Observational environment of part townchip was not standard and the temperature fluctuation was larger, might be one of the reasons causing the low forecast accuracy of the township.With the improvement of the observation environment and the temperature forecast quality of Lvshun Station,the accuracy of forecasting the temperature of villages and towns made by this method will also increase.
