Monsoon originates in tropical latitudes:

  • Wet warm summers - winds from sea
  • Cold dry winter s- winds from continent
  • Transport heat and moisture between latitudes

Convection causes convergence of boundary layer air flow (ITCZ) 

  • Low pressure occurring at ITCZ (condensation and rain) 
  • High pressure at sinking zone (dry conditions between Ferrell and Hadley cells)
  • Convection driven by moist static energy (hm)
