下。众.1 (a】 Numerical solutions: Moisture effect* Dry circulation Upward branch of the MOIST Hadley cell becomes much narrower and more intense than the downward branch due to the enhanced efficiency of moist convection. Mild condensation (c) Strong condensation (Vallis,2006) 授课教师：张洋21授课教师：张洋 21 Hadley Cell : Moisture effect* 4.3 More realistic models of the Hadley circulation 99 Fig. 4.11. Schematic illustration of the effects of including moisture in the Held-Hou Hadley cell model: (a) dry case; (b) some incoming energy evaporates water; (c) all incoming radiation evaporates water. Dry circulation Strong condensation Mild condensation Upward branch of the MOIST Hadley cell becomes much narrower and more intense than the downward branch due to the enhanced efficiency of moist convection.
