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?

It shows up as a change in airspeed. If the airspeed decreases, the pilot
usually reacts by lowering the nose.

2. And does windshear show up as a distinct feature in the flight
weather radar?

I've been told that windshear can be detected on some types of doppler radar,
and that some airports have this. AFAIK, no radar on an aircraft can detect
windshear.
