How is your weather vocabulary? Do you know what convection is? Wind shear? And what the heck is a trough?Hereneat little cheat sheet to help you navigate through the tropical terminology:Center of Circulation -- The area of low pressure in a tropical cyclone.Computer Model -- Mathematical computations that predict the future track of storm.Convection -- Storms.Cyclonic -- The counter-clockwise spin with a tropical system.Millibar -- A unit of measure for pressure. The lower the pressure, the more fierce a storm's winds will be.Outer Bands -- The spirals of rain that wrap around the center of a tropical storm.Sea Surface Temperatures -- Warm water that is the fuel for the storm.Stalling -- When a storm stops its forward motion, making the forecast hard to predict.Trough -- Low pressure, convection, rain.Vertical Stacking -- Tropical systems need low pressure at the earth's surface, and high pressure in the upper levels. Such conditions keep a storm properly ventilated. If not, it will remain weak.Water Vapor Imagery -- Functions as a type of X-ray view on our maps. It indicates where dry air is.Wind Shear -- Winds that change with height that can tear a tropical system apart.
