摘要
2009年7月22日,杭州国家基准气候站进行日全食前、中、后三次的高空对比观测,探究日全食对高空气象要素的影响。观测结果表明,在20000余米高空的同一高度上,有无太阳辐射的温度差异在0.6~3.0℃之间,变化较明显,气压、湿度变化不明显,主要是受仪器误差和日变化影响;地面温度最大差值为2.3℃,变化较明显,气压、湿度变化不大,主要是仪器误差和日变化影响造成的。
On July 22,2009,Hangzhou National Reference Climatological Station carried out three upper air comparative observations before,during and after the total solar eclipse,and explored the effect of total solar eclipse on upper air meteorological elements.Observation results show that at the same height of about 20,000-meter upper air,temperature difference between the place with solar radiation and the place without solar radiation is 0.6-3.0℃,which is obvious;Changes of air pressure and humidity are unobvious,mainly affected by instrument errors and diurnal changes.Maximum difference of ground temperature is 2.3℃,which is obvious;Changes of air pressure and humidity are unobvious,mainly affected by instrument errors and diurnal changes.
