If the monthly THI was less than 75 degrees, then a value of 0 wasĪssigned to the month. A THI value was calculated for each month using theĪverage maximum temperature and the average afternoon relative humidity. = Td-(0.55-0.55RH)(Td-58) where Td is the dry bulb temperature and RH is Percent of possible sunshine data, with only 158 stations having all theīecause of the strong relationship betweenĭiscomfort due to high temperature and high humidity, it was decidedĬombine these factors using the temperature-humidity index (THI) using THI The most limiting factor was the lack of data for the Particular, some stations do not regularly record relative humidity and sunshine. Meteorological parameters are available for all of the stations. This represents ninety major urbanĪreas by stations within thirty miles. Has approximately 300 locations from all fifty states, Puerto Rico andġ0 Pacific island stations. The initial Comparative Climatic Data (CCC) analyzed Were combined to derive a monthly temperature humidity index (THI) which Monthly maximum temperature and corresponding afternoon relative humidity Precipitation, mean annual snowfall, average percent of sunshine, and average relative humidity. Temperatures greater than 90º F, mean annual rainfall, mean number of days with Minimum temperatures less than 32º F, mean number of days with maximum These parametersĪre: maximum temperatures, minimum temperatures, mean number of days with Nine different weather elements were used in constructingĪn index of ideal weather a Camelot Climate Index (CCI). What follows is just one person's (the author's) idea that an ideal climate is sunny and relatively mild with few extremes in temperature, humidity or precipitation.ĭata for this project was extracted from theĬomparative Climatic Data for the United States (NCDC,Ģ010) and updated 1981-2010 Normals (2011). Some individuals may want warm beach weather all year round, while four distinct seasons are most desirable for others. Year and by royal decree at that! But actually an "ideal" climate is extremely subjective, with one person's idea of perfection being met with disdain by others. In this 1960's musical King Arthur professes that Camelot has a perfect climate all the
