Abstract

Precipitation (P) can affect the growth, yield and quality of tobacco. This study compares P from the field automatic meteorological station (FMS) and national meteorological station (NMS) which are installed in different sites in Guiyang County, Chenzhou City of south Hunan Province on different time scales (whole year, tobacco-growing season and different tobacco-growing stages). The results show that P, P differences (P), and day numbers of P difference (P < 0 mm, = 0 mm, and > 0 mm) between FMS and NMS are different at different sites and different time scales. The range of P between FMS and NMS are from 20.4 to 339.1 mm with the absolute error from 4.6% to 48.4%, and day number is 0 - 133 d for P < 0 mm, 7 - 191 d for P = 0 mm and 8 - 158 d for P > 0 mm; In most cases the quadratic regression model could describe well the correlation in P between NMS and FMS on different time scales, but the accuracy of the regression model varies with different sites and different time scales. Therefore, it is necessary to determine climate zones firstly for a tobacco-planting region and then FMS should be installed for each zone to obtain the real zonal P data for meeting the requirements of fine meteorological services and revealing more accurately the relationship between climate and the growth, yield and quality of tobacco.
