✦ Synopsis

Following the clearing of native perennial vegetation for agriculture based on winter growing annual species, the surface characteristics of south-western Australia have been significantly altered. Analysis of the annual variation of these characteristics based on satellite data and a one-dimensional boundary layer model suggests that convective mixing over the cleared land is no longer able to reach the lifting condensation level for a significant period of the year. This implies a decrease in convective cloud formation and a reduction in the convective enhancement of rainfall.
