The most recent storm to receive a category 5 ranking is the January 2016 United States blizzard, which scored a value of 20.14. The ...
Meteorology is a branch of the atmospheric sciences (which include atmospheric chemistry and physics) with a major focus on weather forecasting.The study of meteorology dates back millennia, though significant progress in meteorology did not begin until the 18th century.
During the winter solstice, Sun does not rise more than 16.56° above the horizon at midday, but 63.44° in summer solstice above the same horizon direction. The difference in the length of the day between summer and winter, from here to the north, begin to be striking – slightly more than 8 hours at winter solstice, to more than 16 hours ...
The Köppen climate classification is the most widely used climate classification system. [2] It defines a tropical climate as a region where the mean temperature of the coldest month is greater than or equal to 18 °C (64 °F) and does not fit into the criteria for B-group climates, classifying them as an A-group (tropical climate group).

Also actiniform. Describing a collection of low-lying, radially structured clouds with distinct shapes (resembling leaves or wheels in satellite imagery), and typically organized in extensive mesoscale fields over marine environments. They are closely related to and sometimes considered a variant of stratocumulus clouds. actinometer A scientific instrument used to measure the heating power of ...
When will the geomagnetic storm occur? A storm watch is in effect for Dec. 31. CMEs travel several million miles per hour, so the NOAA predicts that the best time to see the lights would be ...
