What Is Cyclonic and Anticyclonic Curavture?

Asked by: 6557 views Weather

I was reading the pressure section (Chapter 3) of the Aviation Weather for Pilots (AC 00-6A) and couldn't understand "cyclonic curvature."

LOW-a center of pressure surrounded on all sides by higher pressure; also called a cyclone. Cyclonic curvature is the curvature of isobars to the left when you stand with lower pressure to your left. 2. HIGH-a center of pressure surrounded on all sides by lower pressure, also called an anticyclone. Anticyclonic curvature is the curvature of isobars to the right when you stand with lower pressure to your left.
What (anti)cyclonic curvature is and what is the significance of it? Thank you.
