1. I more or less know the effects of windshear during landing but how
does it affect an aircraft during takeoff, if at all? Will it induce a
reduced angle of climb?

During takeoff an increase in headwind will reduce the distance required for
your aircraft to become airborne and will reduce your groundspeed.

A decrease in headwind will result in a loss in airspeed equal to to the
decrease in wind velocity. Airspeed is fundamental to lift, and lift is
fundamental to takeoff. In practical terms, you wouldn't want to be trying
to clear trees or a bluff from a short field and then suddenly experience a
20 knot shift in airspeed.

I've never seen a weather radar screen so I don't know how windsheer might
be depicted. My guess is it's not; in recent decades they have developed
windsheer detection equipment for that specific purpose, which suggests
there was an inability to do so with conventional weather radar.
