On A Global Scale Where Is Precipitation Most Common


On A Global Scale Where Is Precipitation Most Common?

Precipitation is most abundant where air rises and least abundant where it sinks. It also tends to be greater near oceans and lakes and in higher elevations.

Which layer has the most precipitation?

The Troposphere

It contains most of our weather – clouds rain snow. In this part of the atmosphere the temperature gets colder as the distance above the earth increases by about 6.5°C per kilometre. The actual change of temperature with height varies from day to day depending on the weather.

What is the global amount of precipitation?

990 millimetres

Approximately 505 000 cubic kilometres (121 000 cu mi) of water falls as precipitation each year 398 000 cubic kilometres (95 000 cu mi) of it over the oceans. Given the Earth’s surface area that means the globally averaged annual precipitation is 990 millimetres (39 in).

Why is precipitation high at the equator?

Near the Earth’s equator solar heating is intense year round. The Sun heats the ocean evaporating tremendous amounts of water. … As air rises it cools and water vapor condenses into rain. This daily cycle of heating evaporation and convection creates a persistent band of showers and storms around Earth’s middle.

Where does it rain the most in the world?

Where does it rain the least in the world?

The driest place on Earth is in Antarctica in an area called the Dry Valleys which have seen no rain for nearly 2 million years. There is absolutely no precipitation in this region and it makes up a 4800 square kilometer region of almost no water ice or snow.

Where is the annual precipitation highest?

Mawsynram located in the Meghalaya State in India is the wettest place in the world. It receives an annual rainfall of 11 871 millimeters. The mountainous terrain of the surrounding land forces the northward-moving warm moist monsoon winds coming from the Bay of Bengal to converge over Mawsynram.Mar 27 2019

Where do you find precipitation data?

General Information. The precipitation data are quality-controlled multi-sensor (radar and rain gauge) precipitation estimates obtained from National Weather Service (NWS) River Forecast Centers (RFCs) and mosaicked by National Centers for Environmental Prediction (NCEP).

How does the total amount of global precipitation compare to the total amount of global evaporation?

On a global scale the amount of water evaporating is about the same as the amount of water delivered to the Earth as precipitation. This does vary geographically though. Evaporation is more prevalent over the oceans than precipitation while over the land precipitation routinely exceeds evaporation.

What is the most common rainfall in tropical areas?

Description. Tropical rain forests have a type of tropical climate in which there is no dry season—all months have an average precipitation value of at least 60 mm (2.4 in).

Why is precipitation more abundant on one side of the mountain?

Because rising air cools and condenses precipitation is heaviest on the upwind side of a mountain where the air is rising.

Which areas receive the least amount of precipitation?

The least rainy portion of the nation takes in a broad swath of southeast California extending from Death Valley south to the Mexican border. The most arid area also crosses the state border into Nevada and straddles the Colorado River in the southwest corner of Arizona. Two deserts occupy this region.

Where does it rain the most in Canada?

Abbotsford British Columbia tops the list with an average 1538 millimetres about five feet of precipitation falling annually. But Abbotsford isn’t even among the top three cities for most days a year with precipitation. That honour falls to St. John’s Newfoundland along with Saguenay and Sherbrooke in Quebec.

How do you read a precipitation chart?

The average temperature for each month is plotted on the graph with a red dot and the dots are then connected in a smooth red line. Precipitation (mm) is measured using the numbers on the right hand side of the chart. The average rainfall for each month is plotted on the graph with a blue bar.

What do you know about precipitation?

Precipitation is any liquid or frozen water that forms in the atmosphere and falls back to the Earth. It comes in many forms like rain sleet and snow. … Precipitation forms in the clouds when water vapor condenses into bigger and bigger droplets of water. When the drops are heavy enough they fall to the Earth.

How do you read the percentage of precipitation?

How do forecasters arrive at this value? Mathematically PoP is defined as follows: PoP = C x A where “C” = the confidence that precipitation will occur somewhere in the forecast area and where “A” = the percent of the area that will receive measurable precipitation if it occurs at all.

Where does most of the precipitation come from?

Most precipitation occurs within the tropics and is caused by convection. The movement of the monsoon trough or intertropical convergence zone brings rainy seasons to savannah regions. Precipitation is a major component of the water cycle and is responsible for depositing fresh water on the planet.

What percent of global precipitation falls on land compared to the oceans?

Evapotranspiration from land — in context

Of the global rainfall amount 77 percent of precipitation falls over oceans and 23 percent over continents. Because some continental precipitation runs off to the seas 83 percent of global evaporation comes from the oceans and only 17 percent from continents.

Which of these receives a larger percentage of global precipitation oceans or continents?

The ocean holds 97% of the total water on the planet 78% of global precipitation occurs over the ocean and it is the source of 86% of global evaporation.

In summer the temperature is between 25 °C – 30 °C while in winter the temperature is between 20 °C – 30 °C. The annual precipitation is between 700 to 1000 mm. The driest months are from November to March and they have less than 60 mm of rainfall.

What is the average precipitation in the tropical rainforest?

2 000 to 10 000 millimeters
Precipitation. Rainforests receive the most rain of all of the biomes in a year! A typical year sees 2 000 to 10 000 millimeters (79 to 394 inches) of rain per year.

What is the average precipitation in a tropical climate?

The average rainfall in the rain forest is the highest for any ecoregion on Earth. The climate in tropical rain forests is constantly warm and moist. The average rainfall in most rain forests is very heavy about 200–450 centimeters (80–180 inches) per year.

Which side of the mountain often receives the most precipitation?

The windward receives more precipitation than the leeward.

Which side of the mountain would you expect there to be greater precipitation?

When air runs into a mountain the side of the mountain that it hits first is called the windward side. This is where air is forced to rise and this is the side of the mountain that often sees the heaviest precipitation.

Why is there more precipitation at higher elevations?

Elevation affects precipitation significantly especially in a mountain environment. On the windward side of a mountain precipitation is increased. As air parcel rises due to increasing elevation on the windward side of the mountain the air parcel cools condenses and it rains.
