Easy to Use Online Document Filter
Online platform allows for less bulky application. Some users liked that it was online and they didn't have to have an expensive bulky app like Adobe.
There are some features lacking and the website could use a little reboot. For the price, you can't get any better than this but it could still look better. It would be easier to use.

First, the website works really well - lots of options to accomplish any task, pretty easy navigation, and reasonable pricing (one-time use is even free!). **************** is outstanding.

What is the general circulation model of the atmosphere?
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 NavierStokes equations on a rotating sphere with thermodynamic terms for various energy sources (radiation, latent heat).
What is the general circulation of 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.
What is the effect of rotation of the earth on the general circulation of 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.
What is the main driver of atmospheric circulation?
Atmospheric circulation. Atmospheric circulation is the movement of air at all levels of the atmosphere over all parts of the planet. The driving force behind atmospheric circulation is solar energy, which heats the atmosphere with different intensities at the equator, the middle latitudes, and the poles.
What causes atmospheric circulation?
Air in the atmosphere moves around the world in a pattern called global atmospheric circulation. ... This pattern, called atmospheric circulation, is caused because the Sun heats the Earth more at the equator than at the poles. It's also affected by the spin of the Earth. In the tropics, near the equator, warm air rises.
What is a regional climate model?
A regional climate model (Abbreviated RCM) is a numerical climate prediction model forced by specified lateral and ocean conditions from a general circulation model (GCM) or observation-based dataset (reanalysis) that simulates atmospheric and land surface processes, while accounting for high-resolution topographical ...
What is a regional climate?
The climate at a given location on Earth is the regional climate. Regional climate depends on the temperature, precipitation, and winds experienced over the long term at that location. ... This leaves less moisture in the air mass available for precipitation on the other side of the mountains.
How do you model climate?
Climate models use quantitative methods to simulate the interactions of the important drivers of climate, including atmosphere, oceans, land surface and ice. They are used for a variety of purposes from study of the dynamics of the climate system to projections of future climate.
What causes global circulation?
Air in the atmosphere moves around the world in a pattern called global atmospheric circulation. ... This pattern, called atmospheric circulation, is caused because the Sun heats the Earth more at the equator than at the poles. It's also affected by the spin of the Earth. In the tropics, near the equator, warm air rises.
What is global circulation?
The global circulation can be described as the world-wide system of winds by which the necessary transport of heat from tropical to polar latitudes is accomplished. In each hemisphere there are three cells (Hadley cell, Ferrell cell and Polar cell) in which air circulates through the entire depth of the troposphere.
