- Abstract
In this paper, the spatio-temporal variation characteristics of the daily maximum boundary layer height (BLH) and precipitation (Prec) from 1900 to 2010 are analysed by using ERA-20C reanalysis data with mathematical statistical methods. However, since time-scale variation of boundary layer processes is very short and precipitation is also a discontinuous variable, to further understand the influence of BLH on precipitation, appropriate individual cases need to be selected for more in-depth analysis. These three sub-regions are extreme arid (annual average Prec < 25mm), arid (25mm < annual average Prec <250mm), and semi-arid (250mm < annual average Prec < 500mm), as shown by the white contours in Figure 1. The white contours represent the average annual precipitation from 1900 to 2010, and the shaded colours represents the daily trend rates. gl 1 TableThe climate tendency rate and correlation coefficient (r) between the daily maximum boundary layer height and precipitation in the three sub-regions.
