Conference notebook: Are hurricanes possible in a dry environment?

A hurricane-like vortex is proven possible through a research that it can form and exist in a dry environment. Dry hurricane dynamics maybe related to polar lows and extraterrestrial vortex phenomena and is believed that hurricanes may have formed during the colder periods of Earth's history. Kerry Emanuel's 1986 axisymmetric hurricane intensity theory was the basis being used for the theoretical framework. The key variable in this theory is the entropy where the moisture is included. A series of experiments with the use of a numerical model simulated a single, dry, axisymmetric hurricane with varying environmental forcing conditions.
