Simulating the convective precipitation diurnal cycle in North America’s current and future climate

This is a extensive description of how well a regional climate model at a convection permitting model can represent the diurnal cycle of summer precipitation

... and possible changes in a warmer climate!

What is the diurnal cycle of Precipitation?

Precipitation usually has a favorite time during the day to fall over the ground ... specially in summer.


Model domain

...plus the weather stations to compare precipitation


Amplitude of the diurnal cycle


Phase of the diurnal cycle


What might happen in a warmer climate?

Higher amplitude of the diurnal cycle, meaning more precipitation at its favorite hours.

Along with more intense and more frequent in southern Canada.
