How do I set an updraft in my glider simulation?

In my gilder simulation I need to have an updraft. When your glider is flying it is brought down by wind and gravity. I need an updraft that a player can fly through to bring their glider back up to avoid crashing to the ground. How do I create the updraft when a player flies through the updraft area?

with great difficulty …

Seriously it depends entirely on how your rig works

You could very simply add some code “if … over the updraft area … then add an upwards force”. It’s that simple.
