The strength of the Bise wind can be determined by the analysis of the air pressure difference (in hectopascal [hPa]) between Geneva and Güttingen in canton of Thurgau. The Bise arises as soon as the air pressure in Güttingen (TG) is higher than in Geneva. The greater this air pressure difference, the stronger the Bise blows through the Swiss Plateau. In case of an inverted air pressure difference (low air pressure in Güttingen (TG) and high air pressure in Geneva), the opposite of Bise occurs: The wind blows from southwest through the Swiss Plateau.
