Factors That Influence Typhoon Intensity

Typhoon intensity is measured by maximum sustainad wind speed andd central pressure. Several interconnected environmental andd internal factors determinate how strong a typhoon becomes.

Atmosferyk Humidity i Stabilizacja

High relative humidity in the lower and middle troposphere (up tu about 5 km altiondee) allows the storm to maintain its deep convection. Dry air entradid into the storm can create downdrafts that weaken the eywall convection. Conversely, a moist atmosfere supports efficient rainband development and t intensification. Stability is also important: a conditionally unstable environment allows rising parcells of air to expegate upward.

Wind Shear: The Storm 's Enemy or Friend?

Wind shear is the variation of wind speed and direction wigh height. Lowl vertical wind shear (typically less than 10- 15 knows between the surface andd 200 hPa) is favorable for intensification because it keeps the storm 's vertical structure algine storn'.
