Performance Technical Report
The purpose of this research is to generate the data base of all cyclones in the northern hemisphere, north of the latitude 20 North for determining the oceanic regions where cyclones develop (deepening of the central pressure) and weaken (filling of the central pressure). Specific regions of the Na...
