Temporal Temperature Distribution across Puerto Rico

Based on data retrieved from the National Centers for Environmental Information (NCEI) and using relative frequency distribution analysis, the frequency of extreme Tmax across Puerto Rico is higher during August and October while the frequency of extreme Tmin is higher during January and February. Using the Arc Geographic Information System (GIS)/natural neighbor interpolation technic as well as the 1981-2010 Climate Normals, the warmest day of the year is likely to occur during August, and the coldest day is likely to occur during February. During this process, suspicious climate extremes were identified. Although local climatologist and meteorologist are well aware of these patterns, the general public usually thinks that the highest Tmax occurs during June-July and the coolest Tmin occurs during December-January. Therefore, graphics and maps generated by this research were beneficial as educational material for the general public as well as to report suspicious data.
