Description

It’s a 959 Tropical Storms data of North West Pacific during Last 40 Years (1977-2016). The Folder has Two Excel files, one is "Tropical storm Filtered for homogeneity and Improved for track measurements_1977-2016 for North West Pacific". Its description is: This data represents the Name, Year, ISO time, Latitude, Longitude, Maximum Wind Speed in knots, and Minimum Pressure in hPa. This data has been filtered and improved in for homogeneity: (1) All extratropical storm with cyclogenesis beyond tropical region (0–30 degree N) and all out of the Area of Responsibility (AOR) for the RSMC Tokyo–Typhoon Center (0–60 degree N, 100–180 degree E) were removed (n= 22), (2) All 3–hourly and 1–hourly measured datapoints were removed (good for statistical measurements), and (3) Datapoints of Tropical depression stage (maximum wind speed ≤ 35 knots) in start (cyclogenesis) and end (cyclolysis) of each tropical storm are removed. It contains an overall of 959 tropical storm events. The second excel file is "Tropical Storm track Sinuosity Measurements 1977-2016 for North West Pacific". Its description is: This data represents the Name, Year, Duration, Month, Measured Geodesic tropical storm track length, Measured Geodesic tropical storm length between cyclogenesis and cyclolysis, Tropical Storm track sinuosity (S) = (Geodesic storm complete track distance)/(Geodesic distance between cyclogenesis and cyclolysis locations), and Tropical Storm track Sinuosity Index (SI) = ∛(S-1)×10. Geodesic distance was measured through ArcGIS 10.5. Tropical depression stage (maximum wind speed ≤ 35 knots) in start (cyclogenesis) and end (cyclolysis) of each tropical storm are not taken into consideration. The data is useful to explore the spatio-temporal varying patterns of tracks of tropical storms and article can be used by researchers to further explore the physical mechanism behind the various detected spatio-temporal patterns of tracks of storms in the NWP basin and the same techniques can be applied to other Ocean basins of the world.
