The regime of the rainfall pattern is

  • A. Rainfall throughout the year with a single maximum
  • B. Seasonal rainfall with a single maximum
  • C. Seasonal rainfall with double maxima
  • D. Rainfall throughout the year with double maxima
Correct Answer: Option A
Explanation

A rainfall regime that features rainfall throughout the year with a single maximum refers to a pattern in which rain is distributed across all months, but one month or period receives the greatest amount of precipitation. This pattern can be observed in a variety of climates around the world, though it is most prevalent in temperate and tropical regions.

In a temperate climate, for instance, precipitation may be fairly evenly distributed throughout the year, with a peak during the warmest months, when the evaporation rate is highest, resulting in more cloud formation and, thus, increased precipitation. This may also coincide with regional climate phenomena like monsoons.
