Abstract: | We calculate helicities of solar active regions based on the idea that poloidal flux lines get wrapped around a toroidal flux
tube rising through the convection zone, thereby giving rise to the helicity. We use our solar dynamo model based on the Babcock-Leighton
α-effect to study how helicity varies with latitude and time. |
