Weather: The surprising changes in Canada’s cloud cover

Our changing climate is about far more than just rising temperature and altered precipitation patterns

Canada’s cloud cover is changing. There are more high-level cirrus clouds, more cumulus-type convective clouds, and less low-level stratus type clouds – and that affects our temperature and precipitation.

These surprising results emerge from a new study published by Ewa Milewska, an Environment Canada research climatologist, in a recent issue of the Canadian scientific journal Atmosphere-Ocean.
