Continuing research done by Nogueira, this project gives an in-depth analysis of tropical cyclones and hurricanes from 2012-2022. Tropical cyclones are known to be changing throughout the years, through rainfall volume, forward storm velocity, area, strength, and frequencies. 57 storms in total are examined throughout the ten year paper using Geographic Information systems to plot each storm. United States Historical Climatology Network (USHCN) stations were plotted on the eastern half of the state, where daily precipitation data is pulled from for each storm. Characteristics examined through this study are rainfall rate, rainfall volume, storm forward velocity, intensity, and frequency. Tropical cyclones are then further analyzed through Kriging using ArcGIS Pro. Analysis was done from 1960 - 2010, and this project is used to compare how tropical cyclones and hurricanes have evolved since then. Also examined are El Nino oscillation contributors and how ENSO plays a role in tropical cyclone intensity and frequencies. With the analysis done so far, Tropical Cyclones are much slower and more frequent in the examined ten year period.
