The standard method for estimating tropical cyclone (TC) intensity is by interpreting TC structure from geostationary satellite images, except when aircraft reconnaissance flights are routine. Since much of a TC life cycle occurs over an ocean, satellites are an excellent source of meteorological information for the task as it offers coverage much better than traditional observations. While satell ... More
