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?

Yes -- windshear will appear as a sudden decrease (or increase) in
airspeed, which manifests itself as reduced (sometimes to negative) ROC.

It takes thrust to overcome a windshear.




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


No -- radar detects only precipitation or other, solid, objects.



A link to any site that explains the mechanics of a windshear would be
welcome.
