How does the atmosphere affect the weather?
It stores vast quantities of energy gained in evaporation and it has a profound effect on the weather processes. Without it, there would be no clouds or rain. The amount of moisture in the atmosphere varies widely. When the atmosphere is warm, it can hold more water vapor then when it is cold.
What is atmosphere and effect to our weather system?
As a basic definition, weather is the state of the atmosphere. Most weather occurs in the troposphere, or the lowest layer of the atmosphere. Weather elements form a chain reaction, as the impacts do not remain solely in the atmosphere. Temperature, pressure and humidity (moisture) can interact to form clouds.
How do weather systems work?
The local weather conditions that we experience at the Earth’s surface are related to these air masses and fronts. High in the atmosphere, narrow bands of strong wind, such as the jet streams, steer weather systems and transfer heat and moisture around the globe.
What causes weather in the atmosphere?
Weather occurs primarily due to air pressure, temperature and moisture differences between one place to another. These differences can occur due to the sun angle at any particular spot, which varies by latitude from the tropics.
What are the effects of the atmosphere?
Not only does it contain the oxygen we need to live, but it also protects us from harmful ultraviolet solar radiation. It creates the pressure without which liquid water couldn’t exist on our planet’s surface. And it warms our planet and keeps temperatures habitable for our living Earth.
How can an atmosphere lead to different weather and climates on a planet?
Part of Hall of Planet Earth. Energy from the Sun drives climate by heating Earth’s surface unevenly. The temperature difference sets the ocean and atmosphere in motion as they work together to distribute heat around the planet. Movement of heat by the atmosphere and ocean gives rise to climate and weather.
What is atmosphere climate?
climate, conditions of the atmosphere at a particular location over a long period of time; it is the long-term summation of the atmospheric elements (and their variations) that, over short time periods, constitute weather. Climate is not just the “average weather” (an obsolete, and always inadequate, definition).
What happens in the atmosphere?
The atmosphere is an important part of what makes Earth livable. It blocks some of the Sun’s dangerous rays from reaching Earth. It traps heat, making Earth a comfortable temperature. And the oxygen within our atmosphere is essential for life.
What layer of the atmosphere does weather occur?
Troposphere
Troposphere. Known as the lower atmosphere almost all weather occurs in this region. The troposphere begins at the Earth’s surface and extends from 4 to 12 miles (6 to 20 km) high. The height of the troposphere varies from the equator to the poles.
What is weather forecasting system?
Weather forecasting is the application of current technology and science to predict the state of the atmosphere for a future time and a given location. Numerical weather prediction models are computer simulations of the atmosphere.
Where does weather occur in the atmosphere?
Troposphere. Known as the lower atmosphere almost all weather occurs in this region. The troposphere begins at the Earth’s surface and extends from 4 to 12 miles (6 to 20 km) high. The height of the troposphere varies from the equator to the poles.
What are atmospheric features?
The atmospheric features include coastal wind fields, wind fronts, atmospheric gravity waves, atmospheric boundary layer rolls, atmospheric vortices, polar lows, hurricanes/typhoons, and rain cells.
How does the atmosphere affect the weather system?
High in the atmosphere, narrow bands of strong wind, such as the jet streams, steer weather systems and transfer heat and moisture around the globe. As they travel across the Earth, air masses and global winds do not move in straight lines.
How is the temperature of the atmosphere related to the temperature at the surface?
The atmosphere in turn, is heated indirectly by conduction and convection of heat and long-wave radiation from the earth�s surface. Thus, the temperature at the surface is higher than it is in the atmosphere and the temperature in the atmosphere generally decreases the higher you go.
How are air masses and fronts related to weather?
The local weather conditions that we experience at the Earth’s surface are related to these air masses and fronts. However the environment far above us impacts their movement. High in the atmosphere, narrow bands of strong wind, such as the jet streams, steer weather systems and transfer heat and moisture around the globe.
How does heat get into the atmosphere from the Sun?
A large amount is also used in the evaporation of surface moisture and is transmitted into the atmosphere as latent heat. The earth�s surface is heated directly by radiation from the sun. Dark surfaces (Ex. a burned area) generally absorb more of the radiation than light surfaces and will become hotter.
