Peninsula-scale convergence in the south Florida sea breeze.

Abstract

Computations of peninsula-scale convergence in southern Florida reveal that daily-averaged surface convergence on sea-breeze days with relatively little rainfall is larger than on days with widespread rain. This negative correlation between surface convergence and area-averaged rainfall occurs a result of significantly less surface convergence in the late afternoon and early evening on those days with consideable rainfall. The observations suggest that both the magnitude and timing of the convective response to the sea-breeze forcing during the afternoon are very sensitive to the moisture amount and somewhat less sensitive to the thermal stablity in the midtroposphere. - from Author
