What is a heat wave? What defines it and how is it formed?

New York (WABC)-The heat wave of summer once hit us, and temperatures soared in the 90’s, giving us a three-digit feeling.

But what is a heat wave? What defines it and how is it formed?

When the high pressure system moves into the area and stops, heat waves can form.

This system can force warm air downwards and acts like a cap that keeps cold air near the surface from rising.

What is considered a heat wave varies widely from region to region, but in the northeastern or Great Lakes regions, heat waves are usually thought to include three consecutive days of temperature over the 1990s.
