Simple is good: How we understand climate using idealised models
The first satellite image was from the ESA-MSG-4 geostationary weather satellite (link). Second image is from Earth.nullschool, showing a forecast for the earth's wind at 250hPa (link). The last image shows fictional results of a simplified qg like model, image is photoshopped from the gqs model outputs. The figure was designed by Oisin Hamilton.

Do you gravitate to science because of the subject’s ability to explain complicated behaviour in nature through experimentation? When we see things or get our hands dirty by conducting experiments, it helps us comprehend scientific theories which are harder to explain. Introducing a complicated scientific theory is often carried out initially by presenting a simplified version.  For example, stude ...[Read More]

After decades of observation, one of the profound consequences of anthropogenic global warming is the rapid rise in temperature in the Arctic, refered to as Arctic Amplification. Compared to the mid-latitudes, warming in the Arctic is twice as fast. The reason is mainly due to the positive feedback of a melting cryosphere: Darker surfaces are revealed from melting cryosphere, reflecting less short ...[Read More]
