The K-Index or George's Index is a measure of thunderstorm potential in meteorology. According to the National Weather Service, the index harnesses measurements such as "vertical temperature lapse rate, moisture content of the lower atmosphere, and the vertical extent of the moist layer." [1] It was developed by the American meteorologist ...
Weather. Cloud physics is the study of the physical processes that lead to the formation, growth and precipitation of atmospheric clouds. These aerosols are found in the troposphere, stratosphere, and mesosphere, which collectively make up the greatest part of the homosphere. Clouds consist of microscopic droplets of liquid water (warm clouds ...
Weather reconnaissance aircraft, such as this WP-3D Orion, provide data that is then used in numerical weather forecasts.. The atmosphere is a fluid.As such, the idea of numerical weather prediction is to sample the state of the fluid at a given time and use the equations of fluid dynamics and thermodynamics to estimate the state of the fluid at some time in the future.
A surface weather analysis for the United States on October 21, 2006. By that time, Tropical Storm Paul was active (Paul later became a hurricane). Surface weather analysis is a special type of weather map that provides a view of weather elements over a geographical area at a specified time based on information from ground-based weather stations.
The history of surface weather analysis concerns the timetable of developments related to surface weather analysis. Initially a tool of study for the behavior of storms, surface weather analyses became a work in progress to explain current weather and as an aid for short term weather forecasting. Initial efforts to create surface weather ...
Weather map. A surface weather analysis for the United States on October 21, 2006. A weather map, also known as synoptic weather chart, displays various meteorological features across a particular area at a particular point in time and has various symbols which all have specific meanings. [1] Such maps have been in use since the mid-19th ...
College of DuPage is a public community college with its main campus in Glen Ellyn, Illinois. [3] The college also owns and operates satellite campuses in Addison, Carol Stream, Naperville and Westmont. [4][5] With more than 20,000 students, the College of DuPage is the second largest provider of undergraduate education in Illinois, after ...
Tephigram. A tephigram is one of a number [Note 1] of thermodynamic diagrams commonly used in weather analysis and forecasting. The name evolved from the original name "T- -gram" to describe the axes of temperature (T) and entropy ( ) used to create the plot. [1] Usually, temperature and dew point data from radiosondes are plotted on these ...
