Clunckdriver. This "old chap" must be losing it. The only weather books truly dedicated to Canadian pilots are: ACWM (Air Command Weather Manual), AWARE and Weather Ways all of which were first published decades ago. And they are all great books!
I am not aware of the new weather books you mentioned appearing "every year or two." As an airline pilot/meteorologist/writer/author and weather instructor for 30 years I tend to keep on top of this, but obviously not well enough. Thanks for the heads up.
True a brand new aviation weather book has been published the same time mine has. But, I am certain both books will do well.
All the best!
