Comparative analysis on meteorological parameters of sounding data and model-generated sounding data
摘要
Abstract
By using the NCEP/NCAR global reanalysis data with sounding observation data over Fuyang and Anqing from Nov. Of 2007 to Nov. Of 2008, we compared and analyzed the data consistency between two sets of data based on the Lagrange interpolation in vertical direction and horizontal bilinear interpolation of NCEP data. The results showed that the absolute errors of temperature, relative humidity, u wind and v wind between these two data changed a little in different locations, heights and seasons. The range of meteorological parameters absolute error (0. 5-8 km) was as follows; 0. 5-1. 0 degree (temperature) , 5%-15% (relative humidity) , 1-3 m/s (u wind) , 1-4 m/s (v wind) , which is relatively stable, so that NCEP data can be used to analyze the characteristic of meteorological parameters in areas without observational data. However, the absolute error close to the ground is larger than that from 0. 5 km to 8 km.关键词
