Global Precipitation Patterns
Global Precipitation Patterns
Types of Precipitation [1]
Precipitation is any type of water that forms in the Earth’s atmosphere and then drops onto the surface of the Earth.. Water vapor, droplets of water suspended in the air, builds up in the Earth’s atmosphere
Water vapor collects with other materials, such as dust, in clouds.. Precipitation condenses, or forms, around these tiny pieces of material, called cloud condensation nuclei (CCN).
It eventually evaporates and rises back into the atmosphere as a gas. In clouds, it turns back into liquid or solid water, and it falls to Earth again
Precipitation [2]
In meteorology, precipitation is any product of the condensation of atmospheric water vapor that falls from clouds due to gravitational pull.[2] The main forms of precipitation include drizzle, rain, sleet, snow, ice pellets, graupel and hail. Precipitation occurs when a portion of the atmosphere becomes saturated with water vapor (reaching 100% relative humidity), so that the water condenses and “precipitates” or falls
Two processes, possibly acting together, can lead to air becoming saturated: cooling the air or adding water vapor to the air. Precipitation forms as smaller droplets coalesce via collision with other rain drops or ice crystals within a cloud
Moisture that is lifted or otherwise forced to rise over a layer of sub-freezing air at the surface may be condensed into clouds and rain. This process is typically active when freezing rain occurs
What is the heat index? [3]
That’s a partly valid phrase you may have heard in the summer, but it’s actually both. The heat index, also known as the apparent temperature, is what the temperature feels like to the human body when relative humidity is combined with the air temperature
When the body gets too hot, it begins to perspire or sweat to cool itself off. If the perspiration is not able to evaporate, the body cannot regulate its temperature
relative humidity) is high, the rate of evaporation from the body decreases. In other words, the human body feels warmer in humid conditions
Climate – World Precipitation, Distribution, Meteorology [4]
– The role of the biosphere in the Earth-atmosphere system. The yearly precipitation averaged over the whole Earth is about 100 cm (39 inches), but this is distributed very unevenly
Middle latitudes receive moderate amounts of precipitation, but little falls in the desert regions of the subtropics and around the poles.. 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
In the subtropics, the trade winds bring plentiful rain to the east coasts of the continents, but the west coasts tend to be dry. On the other hand, in high latitudes the west coasts are generally wetter than the east coasts
[Solved] The annual range of temperature in the interior of the conti [5]
The annual range of temperature in the interior of the continents is high as compared to coastal areas. Variation in altitude between continents and oceans
– One major factor affecting the distribution of the temperature of Earth is the distribution of Land and Oceans.. – Since there is more land in Northern Hemisphere and more water in the Southern hemisphere and there is a big difference between the specific heat of land and water; the loss of heat from the continents is bigger than the oceans.
– This is the reason that the temperatures of the Oceans are moderate while that of continents is extreme.. – The moderating effect on the temperature of the land due to the proximity of the seas is called Maritime influence.

as long as its temperature is higher than that of the surrounding air. as long as its temperature is the same as that of the surrounding air
is pretty constant from place to place around the globe. varies in space but doesn’t show much variation at any one place over time
is about the same as the total volume of liquid water in lakes, rivers, wetlands, and soil moisture. is only about 1/1000 of 1% of the total volume of water on the globe, but is important because it cycles through the atmosphere very rapidly with an average residence time of only 7 to 9 days
AR4 WGI Chapter 11: Regional Climate Projections [8]
Do Projected Changes in Climate Vary from Region to Region?. This variation is driven by the uneven distribution of solar heating, the individual responses of the atmosphere, oceans and land surface, the interactions between these, and the physical characteristics of the regions
Some human-induced factors that affect climate (‘forcings’) are global in nature, while others differ from one region to another. For example, carbon dioxide, which causes warming, is distributed evenly around the globe, regardless of where the emissions originate, whereas sulphate aerosols (small particles) that offset some of the warming tend to be regional in their distribution
Thus, the projected changes in climate will also vary from region to region.. Latitude is a good starting point for considering how changes in climate will affect a region

Differences in temperature or precipitation determine the types of plants that grow in a given area (Figure 1). Generally speaking, height, density, and species diversity decreases from warm, wet climates to cool, dry climates
One such system was based on the location of the perennating organ (Table 1). These are tissues that give rise to new growth the following season, and are therefore sensitive to climatic conditions
In fact, life form spectra are more alike in similar climates on different continents than they are in different climates on the same continent (Figure 3). Regions of similar climate and dominant plant types are called biomes

Atmosphere – Effect of continents on air movement [11]
Preferred geographic locations exist for subtropical ridges and for the development, movement, and decay of extratropical cyclones. During the winter months in middle and high latitudes, the lower parts of the troposphere over continents often serve as reservoirs of cold air as heat is radiated into space throughout the long nights
Warm currents transport heat from lower latitudes poleward and tend to occur on the western sides of oceans. The lower troposphere over these warmer oceanic areas tends to be a region of relative low pressure
Over Asia in particular, the cold high-pressure system is sufficiently permanent that a persistent offshore flow called the winter monsoon occurs.. An inverse type of flow develops in the summer as the continents heat more rapidly than their adjacent oceanic areas
Desert [12]
Deserts are areas that receive very little precipitation.. Biology, Ecology, Earth Science, Geology, Meteorology, Geography, Human Geography, Physical Geography, Social Studies, World History
People often use the adjectives “hot,” “dry,” and “empty” to describe deserts, but these words do not tell the whole story. Although some deserts are very hot, with daytime temperatures as high as 54°C (130°F), other deserts have cold winters or are cold year-round
People have adapted to life in the desert for thousands of years.. One thing all deserts have in common is that they are arid, or dry

8. Air Masses and Fronts [15]
The day-to-day fire weather in a given area depends, to a large extent, on either the character of the prevailing air mass, or the interaction of two or more air masses.. The weather within an air mass—whether cool or warm, humid or dry, clear or cloudy—depends on the temperature and humidity structure of the air mass
As an air mass moves away from its source region, its characteristics will be modified, but these changes, and the resulting changes in fire weather, are gradual from day to day.. When one air mass gives way to another in a region, fire weather may change abruptly—sometimes with violent winds—as the front, or leading edge of the new air mass, passes
But if it is dry, the fire weather may become critical, if only for a short time.. In chapter 5 we learned that in the primary and secondary circulations there are regions where high-pressure cells tend to form and stagnate
Q. Consider the following statements:Which of the statements given above is [16]
Which of the statements given above is/are correct?. Statement 1 is correct: In Orographic rainfall, the windward side experiences rain due to adiabatic expansion of air while the leeward side remains dry due to the adiabatic compression of air.
But the frontal system can travel to the tropical region causing precipitation there.. Statement 3 is correct: Convectional rainfall occurs mainly in the summer or the hotter part of the day and is very common in the equatorial regions and interior parts of the continents, particularly in the northern hemisphere.
Antarctica Climate & Weather Facts [17]
The average temperature in the interior throughout the year is about -57°C, with the minimum temperature being -90°C during the winter season. Although the coast is warmer and temperatures can reach a maximum of between -2°C and 8°C during the summer
Technically, Antarctica is a desert because it is so dry there; with an average annual precipitation of just 166mm along the coastal regions, and even less when moving further inland. With such cold conditions the snow hardly ever melts; instead, it will mostly become compressed over time to form part of the ice sheet
This ice sheet is, on average, 1.6 km thick and covers about 98% of the entire continent; this is nearly 90% of the entire world’s ice, so it’s no wonder the Antarctic climate is so cold!. Strangely enough, one can suffer serious sunburn whilst there as the snow acts as a reflector which reflects nearly all the ultraviolet rays, so although you may not feel the heat, you still need to make sure to keep your skin safe from the rays.
Biomes of the World [18]
Introduction: Desert areas are rarely devoid of life. Instead, they abound with wonderfully adapted plants and animals that have evolved various mechanisms for tolerating or avoiding the extremes of aridity and temperature that might be encountered in their environment
– Under zones of high atmospheric pressure associated with the subtropics and centered near 30° latitude. Air descending from the upper atmosphere at these latitudes causes evaporation to exceed precipitation
– West coasts of continents between 20° and 30° latitude. In these latitudes, prevailing winds are easterly and prevent moist air from coming onto the west coast
