摘要：
Implemented is the procedure of assimilation of humidity observations in the data assimilation system based on the local ensemble Kalman filter. Applied is the correction of the time lag and solar heating in the process of humidity radiosonde observations. Presented are the results of the assimilation of humidity radiosonde observations and the results of their correction as compared with assimilation without humidity data. It is demonstrated that the use of the correction of humidity observations enables error reduction at the assimilation in the cycle.
