rainy season 7th class essay

Answer:
Explanation:The wet season (sometimes called the rainy season) is the time of year when most of a region's average annual rainfall occurs. Generally the season lasts at least a month.[1] The term "green season" is also sometimes used as a euphemism by tourist authorities.[2] Areas with wet seasons are dispersed across portions of the tropics and subtropics.[3]
Under the Köppen climate classification, for tropical climates, a wet season month is defined as a month where average precipitation is 60 millimetres (2.4 in) or more.[4] In contrast to areas with savanna climates and monsoon regimes, Mediterranean climates have wet winters and dry summers. Dry and rainy months are characteristic of tropical seasonal forests: in contrast to tropical rainforests, which do not have dry or wet seasons, since their rainfall is equally distributed throughout the year.[5] Some areas with pronounced rainy seasons will see a break in rainfall mid-season, when the intertropical convergence zone or monsoon trough moves to higher latitudes in the middle of the warm season.[6]
When the wet season occurs during a warm season, or summer, precipitation falls mainly during the late afternoon and early evening. In the wet season, air quality improves, fresh water quality improves, and vegetation grows substantially, leading to crop yields late in the season. Rivers overflow their banks, and some animals retreat to higher ground. Soil nutrients diminish and erosion increases. The incidence of malaria increases in areas where the rainy season coincides with high temperatures, particularly in tropical areas.[7] Some animals have adaptation and survival strategies for the wet season. Often, the previous dry season leads to food shortages in the wet season, as the crops have yet to mature.
Humans
The wet season is the main period of vegetation growth within the Savanna climate regime.[44] However, this also means that wet season is a time for food shortages before crops reach their full maturity.[45] This causes seasonal weight changes for people in developing countries, with a drop occurring during the wet season until the time of the first harvest, when weights rebound.[46] Malaria incidence increases during periods of high temperature and heavy rainfall.[47]
Animals
Cows calve, or give birth, at the beginning of the wet season.[48] The onset of the rainy season signals the departure of the monarch butterfly from Mexico.[49] Tropical species of butterflies show larger dot markings on their wings to fend off possible predators and are more active during the wet season than the dry season.[50] Within the tropics and warmer areas of the subtropics, decreased salinity of near shore wetlands due to the rains causes an increase in crocodile nesting.[51] Other species, such as the arroyo toad, spawn within the couple of months after the seasonal rains.[52] Armadillos and rattlesnakes seek higher ground
Answer:
Rainy season is the favourite season of almost everyone as it comes after the very hot summer season. The season in which the year’s most annual rainfall occurs is called the rainy season. The extent of rainy season and the amount of rains; however, varies from place to place, depending upon the local topography, wind patterns and other climatic factors. Some places across the globe have rainy season extending up to one to three or may be four months, while the equatorial regions experience wet and dry climate throughout the year. Rains constitute a vital natural resource and are very essential for flora, fauna, agriculture and ecological balance of a place.
Though, a moderate rainy season is the best; too low and too much of rains have its own consequences. A weak rainy season could cause famine and drought while a very strong rainy season may result in floods; nevertheless, annual rainy season is essential for life on planet.
