摘要
利用银川市国家高空气象观测站2020年探空仪换型平行观测期间的探空数据,分别对新型探空仪和换型前探空仪30 hPa以下逐层规定等压面层的位势高度、温度、湿度差值进行了对比分析。结果表明:GTS11,GTS12和GTS13型新型探空仪,其位势高度差值均为负值,且随高度的增加而增大;GTS13型探空仪温度差值随高度的增加基本保持在-0.2℃不变,更接近换型前探空仪测得的温度值;GTS11和GTS13型探空仪的湿度差值较为一致,700 hPa以上为正值,700 hPa以下为负值,湿度差值总体随着高度的增加而增大,至100 hPa时湿度差值逐渐减小;GTS13型探空仪探空平均高度最高,超过考核指标。
The difference of potential height,temperature and humidity of isobaric surface layers under 30 hPa between data gained from the new sonde and the replaced sonde was compared and analyzed,based on the sounding data of Yinchuan National High Altitude Meteorological Observatory during the parallel observation period in 2020.The results show that:the potential height difference of the new sondes of GTS11,GTS12 and GTS13 is negative,and increases with height;the temperature difference of GTS13 basically keeps at-0.2℃with the increase of altitude,which is closer to the temperature measured by the sonde before the changeover;the humidity difference of GTS11 and GTS13 is relatively consistent,which is positive above 700 hPa and negative below 700 hPa,and increases with the increase of height,but gradually decreases when it reaches 100 hPa;and the average height of GTS13 sonde is the highest,exceeding the assessment index.
