Worldwide Weather Extremes, Temperature Extremes

Temperature extremes for any place on Earth are determined by a number of factors, including altitude, latitude and physical characteristics. For an extreme to be recorded, an observation must be made at the precise time and place of occurrence; consequently, more extreme temperatures undoubtedly have occurred.

Rainfall Extremes
The total annual precipitation recorded at a place may vary from year to year. The rainiest places show the greatest variations from year to year in actual amounts. The drier places show the greatest variations taken as a percentage of the mean value. At Cherrapunji (India), for example, the great amount of precipitation in a calendar year was 2,298.9;) cm. The least was 717.80 cm, a difference of 1,581.15 cm. At Arica (Chile), half of the total rainfall recorded from 1931 through 1960 fell in the single year 1949. No rain at all fell in 19 years out of the 30 years. Because of such fluctuations, the average ram precipitation may be greatly influenced by the available years of record; the longer the record, the more reliable is the average.
