What is a climate change model?
What is a Climate Model? Essentially, climate models are an extension of weather forecasting. But whereas weather models make predictions over specific areas and short timespans, climate models are broader and analyze long timespans. They predict how average conditions will change in a region over the coming decades.
How do general circulation models work?
A general circulation model (GCM) is a type of climate model. It employs a mathematical model of the general circulation of a planetary atmosphere or ocean. It uses the Navier–Stokes equations on a rotating sphere with thermodynamic terms for various energy sources (radiation, latent heat).
What are Earth system models?
Earth system models (ESMs) integrate the interactions of atmosphere, ocean, land, ice, and biosphere to estimate the state of regional and global climate under a wide variety of conditions.
What is the global atmospheric circulation model?
The global atmospheric circulation model is a simplified version of how air currents in the atmosphere move. It is used to help explain weather patterns and climatic regions. The global atmospheric circulation model is based around cells. These cells are regions where the air moves from low pressure to high pressure.
What are the 3 atmospheric circulation cells?
The global circulation In each hemisphere there are three cells (Hadley cell, Ferrel cell and Polar cell) in which air circulates through the entire depth of the troposphere. The troposphere is the name given to the vertical extent of the atmosphere from the surface, right up to between 10 and 15 km high.
What causes the circulation cells in the atmosphere?
The circulation of wind in the atmosphere is driven by the rotation of the earth and the incoming energy from the sun. Wind circulates in each hemisphere in three distinct cells which help transport energy and heat from the equator to the poles. The circulation cell closest to the equator is called the Hadley cell.
