How does the atmosphere change the weather?

Tremendous quantities of energy are continuously fed into the atmosphere, setting it into motion and creating weather. Absorption of this energy warms the surface of the earth and heat is exchanged between the earth�s surface and the lower atmosphere.

What are the atmospheric factors that affect weather?

Weather can be defined as the condition of the atmosphere at any given time and place. Weather conditions are determined by six major factors: air temperature, air pressure, humidity of the air, amount and kind of cloud cover, amount and kind of precipitation, and speed and direction of the wind.

How does atmosphere affect the temperature?

The atmosphere today contains more greenhouse gas molecules, so more of the infrared energy emitted by the surface ends up being absorbed by the atmosphere. Since some of the extra energy from a warmer atmosphere radiates back down to the surface, Earth’s surface temperature rises.

How is weather created in the troposphere?

Gravity, combined with the compressibility of air, causes the density of an atmosphere to fall off exponentially with height, such that Earth’s troposphere contains 80\% of the mass and most of the water vapor in the atmosphere, and consequently most of the clouds and stormy weather.

How do atmospheres form?

The surface was molten. As Earth cooled, an atmosphere formed mainly from gases spewed from volcanoes. It included hydrogen sulfide, methane, and ten to 200 times as much carbon dioxide as today’s atmosphere. After about half a billion years, Earth’s surface cooled and solidified enough for water to collect on it.

How does air pressure affect weather in the troposphere?

It is associated with light winds at the surface and subsidence through the lower portion of the troposphere. When pressure increases, more air fills the space left from the low and subsidence evaporates most of the atmosphere’s water vapour. Hence, we can say that the Atmospheric pressure is an indicator of weather.

How does the rain affect the weather?

Humidity and rainfall are important components of the climate of a place. And rainfall is the basic component of the climate,the rainfall occurance mainly decreases the overall temperature and the non-occurance of the rainfall for a long time , increases the overall temperature.

How do meteorologists use the different weather instruments to make an accurate weather report?

Observational data collected by doppler radar, radiosondes, weather satellites, buoys and other instruments are fed into computerized NWS numerical forecast models. The models use equations, along with new and past weather data, to provide forecast guidance to our meteorologists.

What causes different weather conditions?

Weather on Earth is caused by heat from the sun and movement of the air. All weather happens in the lower layer of Earth’s atmosphere, which is a layer of gases surrounding Earth. The sun’s heat warms the air in this layer to different temperature levels in different places.

How does the presence of the tropopause affect weather systems in the troposphere?

The tropopause is the transition between the troposphere and the stratosphere. At the tropopause, an abrupt change in temperature lapse rate usually occurs. The tropopause height is highly variable with latitude, season, and daily. At polar latitudes, the tropopause altitude is nearly 10 km.
