Découvrez la relation entre les termes World et World rainfall distribution comme hyponymes. In the equatorial belt, the trade winds from both hemispheres converge and give rise to a general upward motion of air, which becomes intensified locally in tropical storms that produce very heavy rains in the Caribbean, the Indian and southwest Pacific oceans, and the China Sea and in thunderstorms that are especially frequent and active over the land areas. Results of the numerical application indicate a great variation over the whole country in all different aspects of rainfall. Rain tends to be abundant on the windward slopes of mountain ranges but sparse on the lee sides. Some areas receive high rainfall and some other receive scanty rainfall. De très nombreux exemples de phrases traduites contenant "rainfall distribution" – Dictionnaire français-anglais et moteur de recherche de traductions françaises. World rainfall distribution pourrait avoir un sens plus étroit que World. World distribution of precipitation Regional and latitudinal distribution. The Asian monsoon brings rain to China, Southeast … In these areas, cold and dry winds blow to the continents. Giga-fren. The rainfall is more over the oceans than on the landmasses of the … In this study, data from 813 rainfall stations in Texas are used to update the canonical distributions, which are then extended to include Texas. They absorb the moisture over the land. Rainfall amount and intensity were recorded every 24 hours, while sheet erosion was measured from four tillage systems (Conventional Tillage (CT), Mulch Ripping (MR), … Global distribution of mean annual rainfall (in centimetres). Distribution of rainfall in world depends on the climatic conditions of different regions.

Warm and humid winds when obstructed by a mountain or tableland, they rise along with the slope. In the subtropics, the trade winds bring plentiful rain to the east coasts of the continents, but the west coasts tend to be dry. The dry areas of the subtropics—such as the desert regions of North Africa, the Arabian Peninsula, South Africa, Australia, and central South America—are due to the presence of semipermanent subtropical anticyclones in which the air subsides and becomes warm and dry. In fact, about two-thirds of all rain falls along or near the equator, and countries in those latitudes often have several months of near-daily rain followed by months of dryness as the rain band moves north and south. It was carried out under semiarid conditions and infertile sandy soils of Zimbabwe. Although the monsoons affect most part of India, the amount of rainfall varies from very heavy to scanty on different parts. Distribution of rainfall - definition The western coast and northeastern India receive over about 400 cm of rainfall annually. In Australia, the regions include Western Australia deserts like Great Victoria Desert, Great Sandy Desert and Gibson Desert. This study applies goodness of fit tests to Kemayoran rainfall data. Different places on the earth’s surface receive different amounts of rainfall in a year and that too in different seasons. During the annual cycle, the doldrums move toward the summer hemisphere, so outside a central region near the Equator, which has abundant rain at all seasons, there is a zone that receives much rain in summer but a good deal less in winter. 2014) in Saudi Arabia. Coastal areas have more moisture than interior parts of continents. There is great regional and temporal variation in the distribution of rainfall. Two commonly frequency analysis techniques were used to develop the relationship between the rainfall intensity, storm duration, and return periods from rainfall data for the regions under study. example, the rainfall in the Western Ghats is 200 cm on the windward side The objective is to probe the most fitting distribution for Jakarta. By signing up for this email, you are agreeing to news, offers, and information from Encyclopaedia Britannica. The easterly trade winds, having made a long passage over the warm oceans, bring plentiful rains to the east coasts of the subtropical landmasses, but the west coasts and the interiors of the continents, which are often sheltered by mountain ranges, are very dry. The mean monthly rainfall distribution based on satellite data (TRMM: 3B43 v7) for the period 2000-2012 is presented for comparison purposes. These forms of precipitation or rainfall happens mainly due to the warm era. As temperatures are low, these are called. Convection is there throughout the year (as temperature is high) and hence there is rainfall throughout the year. absorbing the moisture. Because rainfall results from the ascent and cooling of moist air, the areas of heavy rain indicate regions of rising air, whereas the deserts occur in regions in which the air is warmed and dried during descent. The rainfall distribution during the growing season seems to have a considerable influence of the nitrogen supply to the soils. These are cold deserts. When they reach some height, they get cooled 2.3.3.3 Rainfall Distribution Rainfall is an important predictor of the spatial distribution of vegetation in many environments, particularly in transitional zones, such as arid and semiarid environments (Zhao, Gao, Wang, Liu, & Li, 2015). They are very common in Equatorial region. Frigid regions have very low evaporation hence […] These rains are intensified where the air is forced to ascend over the windward slopes of the Western Ghats and the Himalayas. Average Country Rainfall On average, annual rainfall in the Nile basin is approximately 650 mm. 1. The regions include Gobi Desert in Western China, Mongolia and Kazakhstan, Patagonian Desert ( High Plateau region ) in Argentina, Tibetan Plateau, Iranian Previous research has identified five canonical rainfall distributions in the United States; however, identification of these rainfall distributions did not include any rainfall data in the state of Texas. In middle latitudes, weather and rainfall are dominated by traveling depressions and fronts that yield a good deal of rain in all seasons and in most places except the far interiors of the Asian and North American continents. Over 80% of the annual rainfall … World Distribution of Rainfall . Log in. Rainfall distribution was also well fitted by log-Pearson type III distribution in Texas (Salami 2004) and (Lee 2005) in China. The yearly precipitation averaged over the whole Earth is about 100 cm (39 inches), but this is distributed very unevenly. The areas include Greenland, Iceland and North Canada. This study focuses on selecting the best distribution in representing rainfall data from Kemayoran rain gauge (Jakarta, Indonesia) for the last 20 years. The study sought to quantify the effect of rainfall characteristics on sheet erosion and maize grain yield under different tillage systems. Specifically, in fall, rainfall is abundant in the western Mediterranean basin (WM), when the Atlantic jet is relatively strong but its northeasterly tilt is small, and the African jet is in its easternmost position. During the northern summer, when the monsoon blows from the southwest, rainfall is heavy over India and Southeast Asia. These high-pressure belts tend to migrate with the seasons and cause summer dryness on the poleward side and winter dryness on the equatorward side of their mean positions (see below Cyclones and anticyclones). De très nombreux exemples de phrases traduites contenant "distribution of rainfall" – Dictionnaire français-anglais et moteur de recherche de traductions françaises. These forms of precipitation or rainfall happens mainly due to the warm era. Equatorial and rest of the tropical region have highest evaporation and hence highest supply of moisture. 1991) in Ontario and (Alahmadi et al. It is formed due to, In Africa, the regions include Sahara Desert in Chad, Libya, Mauritania, Egypt, Ethiopia and Somalia. Source: World Meteorological Organization WMO data provide the basis for better understanding the climatology of severe weather and extreme events such as tropical cyclones, El Niño, floods, heat waves, cold waves, droughts and other natural hazards, contributing to saving both lives and property, and improving our understanding and monitoring of the climate system and environment. rain: Distribution of Rainfall Enter your search terms: One of the primary elements in climate and a factor of tremendous importance in the distribution of plant and animal life, rainfall varies from less than an inch annually in a desert to more than 400 in. Other maxima exist in western Georgia, northwest Spain, western Great Britain, and western Norway. The average world distribution of rainfall is around 100 cm. Also that technique was applied in Jordan by [15]. hence cools which in turn results in condensation. Rainfall occurs when winds carrying moisture rise up and expansion (adiabatic) takes place and The distribution of rainfall is negligible here. The most obvious pattern in the total rainfall maps is seasonal change. coastal regions. Factors Affecting Rainfall Distribution: Moisture supply to the atmosphere is the main factor in determining the amount of rainfall in any region. There are three types of rainfall around the world namely, Orographic rainfall, Convectional rainfall and Frontal or Cyclonic rainfall. Plateau, Balochistan Plateau, etc. Different types of rainfall are given below. As an Snow or rain occur at times, but evaporation from the cold sea and land surfaces is slow, and the cold air has little capacity for moisture. After the air has traveled some distance over the warm tropical ocean, however, it releases heavy shower rains over the East Indies. Log in. At high latitudes and especially in the polar regions, the low precipitation is caused partly by subsidence of air in the high-pressure belts and partly by the low temperatures. The regions of highest rainfall are found in the equatorial zone and the monsoon area of Southeast Asia. However, it is less than 60 cm in western Rajasthan and adjoining parts of Gujarat, Haryana and Punjab. They are associated with very high rainfall. There the desert in southern Argentina is sheltered by the Andes from the westerly winds blowing from the Pacific Ocean, and the west-coast desert not only is situated under the South Pacific subtropical anticyclone but is also protected by the Andes against rain-bearing winds from the Atlantic. It follows that the rainfall distribution downstream to these cross-jet circulations is strongly influenced by their relative positions. If Earth’s surface were perfectly uniform, the long-term average rainfall would be distributed in distinct latitudinal bands, but the situation is complicated by the pattern of the global winds, the distribution of land and sea, and the presence of mountains. The regions of highest rainfall are found in the equatorial zone and the monsoon area of Southeast Asia. For example, Lagos receives maximum rainfall in May, June and July amounting to 100cm whereas October records … Ask your question. If the surface is covered with dense vegetation, much of the precipitation may be held on leaves and plant limbs and stems. This paper is motivated by the payout mechanism of index insurance which aims at reducing crop losses associated with weather uncertainty in low-income agricultural economies. This is a Map of the World with the Annual Yearly Average Precipitation. Navigate parenthood with the help of the Raising Curious Learners podcast. moisture cannot enter these areas as they are inter-mountainous regions surrounded by hills and mountains. Rainfall is the important element of the Indian economy. It may be evaporated during its fall or after it reaches the ground surface. The coastal areas of the world receive greater amounts of rainfall than the interior of the continents. These deserts are formed because (i) As they are located deep inside the continents, winds become dry by the time they reach there and (ii) Winds carrying A video presentation showing the roles that snow, hail, and the process of orographic lifting play in the hydrologic process. On the other hand, in high latitudes the west coasts are generally wetter than the east coasts. Naghavi and Yu (1995) had chosen the general extreme value (GEV) distribution for Louisiana and similar distribution was opted by (Pilon et al. Nor­mally, April and November receive maximum rainfall but the period of maximum rainfall varies spatially. to, In North America, the regions include Mexican or Mojave Desert. Thus, this study was conducted to analyse the statistical and spatial distribution of rainfall in the KSA over a 30-yr period. Rainfall frequency analysis, based on the generalized extreme value (GEV) distribution along with the L-moments parameter estimation method, was applied to analyze annual maximum rainfall series. On an annual basis, rainfall across the continent is favored within the Alps, and from Slovenia southward to the western coast of Greece. This map shows us different regions in the world, which receives high or low rainfall. In Equatorial region, temperature is high and winds move up. Descending winds never cause rainfall. Rainfall distribution is another factor that has a direct effect on the growth of crops, it can simply be defined as the way rainfall is received through a given rainy season in an area. Gumbel distribution methodology was applied on different region all over the world by [1]. freeboard hydrograph (ESFB) rainfall distribution, 2) The five-point PMP distribution, 3) The critically stacked 24 -hour PMP distribution and 4) The temporal rainfall distribution based on the maximum rainfalls r ecorded on world scale.
