... • TH and TC can be computed from Pavg, because RthHA·CthHA >> tS and RthCH·CthCH >> tS. Hence, the AC component of P can be removed and, therefore: TH = TA + Pavg·RthHA and TC = TH + Pavg·RthCH • However, RthHA·CthHA may be lower than tS and, therefore, TJ cannot be computed from RthJC and Pavg. ...

Heat wave
A heat wave is a prolonged period of excessively hot weather, which may be accompanied by high humidity, especially in oceanic climate countries. While definitions vary, a heat wave is measured relative to the usual weather in the area and relative to normal temperatures for the season. Temperatures that people from a hotter climate consider normal can be termed a heat wave in a cooler area if they are outside the normal climate pattern for that area.The term is applied both to routine weather variations and to extraordinary spells of heat which may occur only once a century. Severe heat waves have caused catastrophic crop failures, thousands of deaths from hyperthermia, and widespread power outages due to increased use of air conditioning. A heat wave is considered extreme weather, and a danger because heat and sunlight may overheat the human body.
