Document Summary
Absolute threshold: heat exceeds certain temperature; cant apply same to all locations: ex: 100 degrees in phoenix is not uncommon, but a 100 degrees in seattle will be devastating. Threshold departures: local appropriate, but some places more variable that other. Percentile departure: useful index for heat in any given location. The best way to measure, because ti account of the fact that a place like boston will have a certain amount if variability, this way requires more math though. On august 12, temps never dropped below 25. 5 c (78 f) Heat waves coupled with a dry heat results in forest res. Shanghai broke all- time record 3x in 3 weeks. Looking back over the decades you look at the record highs and record lows. Projected increases in mean tim on hottest days (once every 20 years) Variation in wind, atmospheric pressure, and sea-surface temps in tropical.
