Players become a powerful convective thunderstorm known as a super-cell, and struggle to collect readings that will lead to the "perfect storm", one capable of generating a sizable tornado. To generate a perfect storm, players need strongly divergent conditions on the ground and the atmosphere. Storms need warm moist air on the ground, cool dry air aloft, and wind shear in the storm column that prevents the cooling downdraft from shutting off the warm and moist inflowing air. The most powerful storms have the lowest air pressure. Will you generate the Perfect Storm?
