Although most precipitation in middle latitudes begins as snow at altitudes above the freezing level (about 3 km/1.8 mi.), the form of the precipitation reaching the surface depends on the temperature structure of the atmospheric layers through which the precipitation falls.

3 Answers. 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.

The relationship between temperature or precipitation and snowpack variability has a linear dependency with altitude, i.e., the influence of temperature (precipitation) decreases (increases) with height.

Relief rainfall, also known as orographic rainfall, occurs in areas where land increases in height.

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. This helps water droplets gather together and become large enough to fall to the Earth.

a : a deposit on the earth of hail, mist, rain, sleet, or snow also : the quantity of water deposited.

Precipitation is rain, snow, sleet, or hail — any kind of weather condition where something’s falling from the sky. Precipitation has to do with things falling down, and not just from the sky. It’s also what happens in chemical reactions when a solid settles to the bottom of a solution.

Precipitation is water released from clouds in the form of rain, freezing rain, sleet, snow, or hail. It is the primary connection in the water cycle that provides for the delivery of atmospheric water to the Earth. Most precipitation falls as rain.

When we talk about precipitation, we are talking about water that is falling out of the sky, this could be rain, drizzle, snow, sleet, hail or something rarer!

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. Precipitation forms as smaller droplets coalesce via collision with other rain drops or ice crystals within a cloud.

If there’s a 10 percent chance of rain, it means the current conditions yield rainfall one out of every 10 times observed. If it’s 20 percent, then you’d see rain two out of every 10 times, and so on. “Summer is a challenging time to forecast the chance of precipitation,” said weather.com meteorologist Chris Dolce.

Global Climate Change. comes from precipitation. Too little precipitation can result in dry soil, shallow streams, and shortages of municipal water supplies. For example, too much rain or snowmelt (water from melted snow) at one time can lead to flooding.

Rainfall and other precipitation washes nutrients from human activities like agriculture and fossil fuel combustion into rivers and lakes. When these nutrients overload waterways, a process called eutrophication, the results can be dangerous.

Greenhouse gas emissions from human activity are causing global shifts in rainfall patterns and contributing to wetter weather over the UK, climate scientists say today. At least half of the extra rainfall and possibly up to 85% is caused by the impact of greenhouse gas emissions, the scientists conclude.

The proximate or immediate cause of a rainfall shortage may be due to one or more factors including an absence of available moisture in the atmosphere; large scale subsidence (downward movement of air within the atmosphere) which suppresses convective activity; and the absence or non-arrival of rain-bearing systems.

This is the first evidence that human activity has altered rainfall patterns. “We expected rainfall patterns to change, but there’s been no conclusive evidence that we are seeing human effects,” says climate researcher Nathan Gillett, of University of East Anglia in Norwich, UK, one of the study’s authors.

As average temperatures at the Earth’s surface rise (see the U.S. and Global Temperature indicator), more evaporation occurs, which, in turn, increases overall precipitation. Therefore, a warming climate is expected to increase precipitation in many areas.

Climate change is making the wettest days wetter, heightening flood risks. Human-caused climate change intensifies the heaviest downpours. More than 70% of the planet’s surface is water, and as the world warms, more water evaporates from oceans, lakes, and soils.

The most immediate impact of heavy precipitation is the prospect of flooding. In addition to flooding, heavy precipitation also increases the risk of landslides. When above-normal precipitation raises the water table and saturates the ground, slopes can lose their stability, causing a landslide.

A warmer climate spurs the evaporation of water from land and sea and allows the atmosphere to hold more moisture—thus setting the stage for more extreme precipitation.

Global precipitation patterns are being moved in new directions by climate change, a new study has found. “But because precipitation has to be balanced by evaporation, we expect a [corresponding] increase in dry regions,” Marvel said. …

The Relationship between Rainfall and Temperature. The physical rationale behind the relationship between rainfall and temperature is that rainfall may affect soil moisture which may in turn affect surface temperature by controlling the partitioning between the sensible and latent heat fluxes [41].

As average temperatures at the Earth’s surface rise, more evaporation occurs, which, in turn, increases overall precipitation. Therefore, a warming climate is expected to increase precipitation in many areas.

The temperature characteristics of a region are influenced by natural factors such as latitude, elevation, and the presence of ocean currents. The precipitation characteristics of a region are influenced by factors such as proximity to mountain ranges and prevailing winds.

The global increase in evaporation is determined by the increase in surface heating and this controls the global increase in precipitation. With higher average temperatures in winter expected, more precipitation is likely to fall in the form of rain rather than snow, which will increase both soil moisture and run off.

Future mean precipitation in the Mediterranean is projected to decrease year-round in response to global warming, threatening to aggravate water stress in the region, which can cause social and economic difficulties.

The Earth’s atmosphere exerts pressure on the surface. Areas of high and low pressure are caused by ascending and descending air. As air warms it ascends, leading to low pressure at the surface. As air cools it descends, leading to high pressure at the surface.
