提利用四川在59-701探空系统向L波段雷达GTS1型电子探空仪系统转变时,就4个高空台站开展了两套系统对比观测的资料进行了差异评估。结果表明:太原厂59型探空仪所测的温度、位势高度比上海厂59型探空仪所测偏高。100 hPa高度以下温度、位势高度观测数据没有明显的跳变,但以上高度换型带来的变化较明显;两套系统所测湿度差异较大,近地面差值最小,差值随高度升高而增大;L波段系统所测湿度基本是低于59-701系统所测湿度。两套系统所测平均风向、平均风速差异较小。直接差异各要素差异的峰值均较大。各要素差值的离散情况随高度的变化各异,总体离散程度最大的是位势高度,其次依次是风向、湿度、露点、风速、温度。两套系统所测要素的差值变化趋势虽然普遍没有太大差异,但湿度、风向和风速的差值变化还是表现出与地理位置、季节和施放时间有关。两套系统在观测所使用设备、原理、精度、订正、观测方法、对比时的放球时间等的不同,都会引起测量值出现差异。

The comparative analysis on observation data of the L-band radar sounding system and 59-701 sounding system by four sounding stations in Sichuan is made in this paper.The results indicate that tem-perature and geopotential height data observed by 59-701 sounding system made in Taiyuan are higher than that observed by 59-701 sounding system made in Shanghai.The temperature and geopotential height data below 100 hPa do not change obviously after using L-band sounding system,but above 100 hPa they change obviously.Humidity data measured by the two sounding systems have large differences.The differences near surface are small,increasing with height.Most of the humidity data measured by L-band sounding system are lower than that measured by 59-701 sounding system.The differences between aver-age wind direction and velocity measured by the two sounding systems are small.Peak value differences of all elements are large.The discrete case of each elements difference changes with different heights.The greatest degree of general discrete is geopotential height,secondly is the wind direction,humidity,dew point,wind speed,and temperature in sequence.The trends of differences between the two sounding sys-tems are not large,but relations exist between the difference changes of humidity,wind direction,wind speed and the geographic location,season,and releasing time.There are differences between L-band and 59-701 sounding systems in equipment,measuring principle,measurement accuracy,the revised statistics, methods of observation,releasing time and so on.
