With a modified Rankine Vortex, the radial profiles of typhoon wind speed in different quadrants (ie. NE, SE, SW and NW) can be represented by a typhoon’s latitude, translation speed and maximum wind speed, which could be regarded as the climatological factors of typhoon’s wind radii. Fitting the Rankine Vortex equation by the historical typhoon data, a regression equation of climatology is obtained by which……   Read the article >>
