===Convective planetary boundary layer (CBL)===
{{Main|Convective planetary boundary layer}}
A convective planetary boundary layer is a type of planetary boundary layer where positive buoyancy flux at the surface creates a thermal instability and thus generates additional or even major turbulence. (This is also known as having CAPE or [[convective available potential energy]]; see [[atmospheric convection]].) A convective boundary layer is typical in tropical and mid-latitudes during daytime. Solar heating assisted by the heat released from the water vapor condensation could create such strong convective turbulence that the [[free convective layer]] comprises the entire troposphere up to the [[tropopause]] (the boundary in the Earth's atmosphere between the [[troposphere]] and the [[stratosphere]]), which is at 10&nbsp;km to 18&nbsp;km in the [[Intertropical convergence zone]]).
