Relationship between rainfall and latitude

Precipitation Rate Versus Latitude and Longitude

relationship between rainfall and latitude

Mar 9, Climate is the prevailing patterns of temperature and precipitation of Capricorn, between 23 degrees north and 23 degrees south latitude, are. Jan 8, My thesis is the temperature of a country can vary on latitude is a lot of rain, and areas around it can range with high and low precipitation.

relationship between rainfall and latitude

This is because fronts stay poleward in summer. The rainfall is more uniformly distributed along east coasts and in the interior in this latitude belt, not because fronts do penetrate into these regions in summer, but because of convective rainfall. Precipitation is heaviest near the ITCZ and in areas where monsoon winds come from over a warm ocean.

Rainfall is less on the lee side of a mountain, as in the case of the Patagonian desert in Argentina, to the east of the southern Andes, where the wind is from the west. It is also less in the Gobi desert in Mongolia, not only because monsoonal moisture is trapped by the Tibetan plateau, but also because frontal systems have lost most of their moisture on their long travel from the Atlantic. Thus, dry conditions imply either a subtropical or polar latitude, an extreme elevation, a rain shadow, situation near an anomalously-cold ocean e.

Such conditions are indicated by low rainfall figures and a large daily range of temperatures It has no meaning at latitudes above If the daily range is large, the atmosphere is dry 18 and there is little cloud, probably indicated by low rainfall figures. Within anticyclones the air is dry and the sky often cloud-free; also, there is little wind, allowing the build-up of a strong nocturnal radiation inversion. Near the ITCZ and in areas frequented by frontal systems, not only does cloudiness limit daytime heating and nighttime cooling, but also, the air is too humid to cool much at night near the ITCZ or too windy at mid-latitudes.

There appears to be no systematic variation of the annual mean daily range with latitude e. The effect of the station elevation h, in km can be isolated: However, it would be better to use Fig 6 directly, as a guide to Rd; in that case, the deduced elevation for a daily range of 12 K would be about 1 km. The broad scatter in Fig 6 is not surprising: Daily ranges at various elevations The horizontal lines show the median values for each band of elevations.

It affects whether the incoming wind is cooled by an west-coast ocean current, it governs whether or not a place is dry because it is far from the upwind ocean as in the Gobi desert, for instanceit determines whether a place is dry because it lies in the lee of a high mountain range or wet because the wind has lately come from a warm ocean.

The direction of the wind depends primarily on the latitude, which is assumed already assessed, at least provisionally, from consideration of the annual temperature mean and range, and precipitation. Winds tend to be light and variable from the equator to about 10 degrees latitude, generally easterly and steady over 10 - 25 degrees, variable between 25 - 35 degrees, mainly westerly but variable over 35 - 60 degrees, variable between 60 and 70 degrees, and easterly nearer the pole 21, Also note what has been said about monsoonal climates.

What is the relationship between temperature and latitude? by Raheel Qamar on Prezi

Procedure In view of all this, one proceeds to estimate the location of the place with a given climate by calculating the annual mean temperature, the annual range and daily range, and by examining the rainfall figures.

Then write down the respective implications of each of these figures, in the light of the considerations above. First try to assess the possible latitude, then the possible elevation, then the distance inland. Finally, from the assessed figure for the latitude, deduce the implied wind direction and check that this is consistent with the temperatures and rainfall at the place provisionally selected.

But bear in mind that local topography may confuse the issue, so that no estimate can be more than indicative. The daily range is 13 K in January and 22 K in July, i. The higher temperatures in January show that the place is in the southern hemisphere.

The value of T implies a sea-level place at 36 degrees latitude, very approximately [i.

How Latitude Affects Climate

Or it might be at a lower latitude and either greater elevation or located near a west coast. Of these options, a coastal location seems unlikely because the daily ranges are high, i. So the place may be elevated, at a latitude less than 36 degrees.

In addition, the apparent annual range of about 3. The orange area is tundra, purple is taiga, green is grassland, black is temperate forest, yellow is desert, blue is tropical rain forest, brown is chaparral and the white is ocean.

The amount of sunlight and the amount of precipitation affects the types of plants and animals that can live in a place. The collection of all the living things in a place, as well as the non-living resources, is called an ecosystem or biome. Listed below are the types of ecosystems that exist in the climates of different latitudes. The most sunlight is received at the equator of our planet, making this area very warm.

The types of ecosystems that develop in this warm environment are: As the name suggests, rainforests receive a lot of rain. Indeed, in some parts of the subtropics, rain may not fall for several years.

The temperate mid latitudes have moderate levels of precipitation, much of it associated with the development of frontal depressions which form when warm subtropical and cold polar air masses collide. On western facing coastlines, annual precipitation may approach inches or 2, millimetres.

This diminishes substantially within the interiors of major landmasses, particularly the continents of North America and Asia, as the air dries and moves further away from its ocean source of moisture. Like temperaturepatterns of rainfall shift with the seasonsand the north-south movement of the Sun, particularly within and near the tropical rain belt.

Regions closest to the equator may experience two wet seasons and two dry seasons. Greatest rainfall occurs at the March and September Equinoxes, when the midday Sun over the equator is directly overhead and is at it strongest.
