Question 2

Which type of fog forms when warm, moist air moves over a cooler surface?

Question 3

The jet stream is located near which atmospheric boundary?

Accepted Answer

The tropopause

Answer

Jet streams occur near the tropopause where strong temperature gradients between air masses create high-speed wind currents.

Question 4

What is a microburst?

Accepted Answer

A concentrated downdraft that produces a short-lived but intense outflow of wind at the surface

Answer

A microburst is an intense downdraft smaller than 4 km in diameter that creates dangerous wind shear close to the ground.
