So lets say that there is region that gets mostly rain during the summer/spring time and snow around fall/winter time, well we all know that climate changes occur to all regions of the world so with the region that mostly gets rain during spring and summer time and snow around fall and winter time will mostly get warm around with no moisture because of the climate changes. If you look at our regions today in the world you can see how much it changed, like some parts of America wasn't suppose to get hit with snowstorms and yet they are, the southwest regions like Arizona and Colorado are receiving less mositure due to climate changes and that's how the droughts occur.
So that's how the climate influence the regions.
Hope this helped :)
Have a great day
