Description
Western North Pacific is the most active TC Basin globally as the season runs whole year round and Sun is the main driver of Earth's Climate, although climate drivers are the ones that affect the typhoon season. As presented in the literature studies, there are few research studies have investigated the relationship between SSN and Tropical Cyclones, but it is done in a specific location or basin. This research will fill in the gap of finding the relationship between SSN and TC in the Western North Pacific as part of the recommendation of the said studies. Datasets that were used were from Japan Meteorological Agency, Solar Influences Data Analysis Center, and National Oceanic Atmospheric Administration. The researcher investigated the relationship between Solar Activity and Tropical Cyclone Frequency with the use of Pearson Correlation, Linear Regression Analysis, and T-Value. The researcher found out that the results of the analysis are mostly in negligible correlation and not significant in terms of overall season, Solar Minimum and Maximum basis, and ENSO phases which concludes that a). there is no overall significant correlation between SSN and WNP-TCF, b). there is no significant correlation between SSN and WNP-TCF during Solar Minimum and Solar Maximum, c). there is no significant relationship between SSN and WNP-TCF during El Nino and La Nina. Thus, this study found out that Sunspot Number doesn’t have much effect to the Tropical Cyclone Frequency in the Western North Pacific Basin and likely that Anthropogenic Aerosols and Climate Oscillators plays the role in the Tropical Cyclone Activity.
