If a large area does not attract moisture, does the moisture go somewhere else?<\/em><\/p>\n https:\/\/en.wikipedia.org\/wiki\/Paso_Robles_Municipal_Airport https:\/\/en.wikipedia.org\/wiki\/California Copernicus shows global surface air temperature variations in video maps like https:\/\/climate.copernicus.eu\/sites\/default\/files\/2024-08\/t2m_video_to_July_2024.mp4 and generally green means cooler, and bare ground and rock means hotter. And asphalt is often dark colored and hot.<\/p>\n The National Weather Service does record some data for Paso Robles Municipal Airport at https:\/\/forecast.weather.gov\/data\/obhistory\/metric\/KPRB.html.\u00a0 I see for 6 Oct 2024 air temperatures of 40.6 C (105.08) but most of the time it is less. Every day the sky has been CLR with no precipitation. With visibility about 16 Kilometers (10 miles). They show readings every hour.<\/p>\n For the three days they show (no download, no archive listed, no data options at all) the average of the hourly temperatures is 25.8194 C and the standard deviation is 8.9456 C.\u00a0 So a maximum temperature of 40.6 C is (40.6 – 25.8194)\/8.9456 = 1.65 standard deviations.<\/p>\n Now do hot areas attract heat?\u00a0 If you live in or near a place with lots of asphalt, no trees, no water, with nothing to slow the wind? What happens most of the time?<\/p>\n Areas store variable amounts of energy, one expects varying temperature pressure wind and moisture<\/em><\/p>\n https:\/\/en.wikipedia.org\/wiki\/Maxwell%E2%80%93Boltzmann_distribution<\/p>\n Richard Collins, The Internet Foundation<\/p>\n","protected":false},"excerpt":{"rendered":" https:\/\/x.com\/PGE_John\/status\/1843090528331763809 If a large area does not attract moisture, does the moisture go somewhere else? https:\/\/en.wikipedia.org\/wiki\/Paso_Robles_Municipal_Airport The Paso Robles Municipal Airport covers about 5.4 km^2 or roughly (2.32 km)^2, and it has large areas of continuously exposed asphalt. https:\/\/en.wikipedia.org\/wiki\/California California has a total area of about 423,970\u00a0km2 km^2, so there are roughly (423,970\/5.4) = 78513
