Proof of global warming in Denver.
Yesterday Denver hit 100 degrees, due to very strong downslope winds coming off the mountains. Normally the spring winds have stopped by now, but everything is running a few weeks late this year due to the long, cold winter.
These hot, dry winds also caused some fires. People build houses in pine forest which normally burns every dozen or so years, and surprisingly the houses burn down.
Katabatic winds?
They are usually called Chinooks here.
I think (when I lived there) I always preferred your first choice of words, above–downslope winds coming off the mountains.
Or where I live people build houses on a sand bar and surprisingly every so often the ocean washes them away.
There are no permanent features on the face of this planet. Leave something in place long enough, and eventually it will be destroyed.
Entropy happens.
