Klimatologi
Klimatologi er læren om klimaet.[1]
Klimatologiens opgave er at beskrive og forklare sådanne fysiske egenskaber i atmosfæren som temperatur, vinde og nedbør samt deres fordeling efter område og sted.
Friedrich Wilhelm Heinrich Alexander von Humboldt regnes som grundlægger af den sammenlignende klimatologi, idet han var den første, som lavede isotermer på grundlag af et stort antal temperaturmålinger[2].

Cyclone Catarina from the ISS on March 26 2004.JPG
Before the year 2004, only two tropical cyclones had ever been noted in the South Atlantic Basin, and no hurricane. However, a circulation center well off the coast of southern Brazil developed tropical cyclone characteristics and continued to intensify as it moved westward. The system developed an eye and apparently reached hurricane strength on Friday, March 26, before eventually making landfall late on Saturday, March 27, 2004.
The crew of the International Space Station was notified of the cyclone and acquired excellent photographs of the storm just as it made landfall on the southern Brazilian state of Santa Catarina (the storm has been unofficially dubbed “Cyclone Catarina”). Note the clockwise circulation of Southern Hemisphere cyclones, the well-defined banding features, and the eyewall of at least a Category 1 system. The coastline is visible under the clouds in the upper left corner of the image.

Mauna Loa CO2 monthly mean concentration NO.svg

This figure shows the history of atmospheric carbon dioxide concentrations as directly measured at Mauna Loa, Hawaii since 1958. This curve is known as the Keeling curve, and is an essential piece of evidence of the man-made increases in greenhouse gases that are believed to be the cause of global warming. The longest such record exists at Mauna Loa, but these measurements have been independently confirmed at many other sites around the world [1]. The annual fluctuation in carbon dioxide is caused by seasonal variations in carbon dioxide uptake by land plants. Since many more forests are concentrated in the Northern Hemisphere, more carbon dioxide is removed from the atmosphere during Northern Hemisphere summer than Southern Hemisphere summer. This annual cycle is shown in the inset figure by taking the average concentration for each month across all measured years. The red curve shows the average monthly concentrations, and blue curve is a smoothed trend. The carbon dioxide data is measured as the mole fraction in dry air. This dataset constitutes the longest record of direct measurements of CO2 in the atmosphere (data up to december 2018).
