Radar image animation of an outflow boundary of a storm approaching Tulsa, Oklahoma. The outflow boundary's weak echo moves left-to-right and passes overhead of the Doppler radar station. The outflow produces a gust front that moves ahead of the main thunderstorm. Outflow, in meteorology, is air that flows outwards from a storm system.
Weather radar in Norman, Oklahoma with rainshaft Weather (WF44) radar dish University of Oklahoma OU-PRIME C-band, polarimetric, weather radar during construction. Weather radar, also called weather surveillance radar (WSR) and Doppler weather radar, is a type of radar used to locate precipitation, calculate its motion, and estimate its type (rain, snow, hail etc.).
Different radar artifacts cluttering the radar display. Clutter [1] [2] is the unwanted return (echoes) in electronic systems, particularly in reference to radars.Such echoes are typically returned from ground, sea, rain, animals/insects, chaff and atmospheric turbulences, and can cause serious performance issues with radar systems.
This scenario leads to increased precipitation and is a fundament behind the idea that the rain belt is moving north. [6] The contrast in temperature is only a part of the entire process that is driving the tropical rain belt northward. [6] Another factor that influences the tropical rain belt is ocean circulation.
On July 29, 2009, a record breaking 333 millimetres (13.1 in) of rain was recorded in Dhaka, in 24 hours, previously 326 millimetres (12.8 in) of rain was recorded on July 13, 1956. [ 11 ] On September 27, 2020, record breaking 433 millimetres (17.0 in) of rain fell just in 12 hours in the city of Rangpur in Northern Bangladesh , producing ...
The climate change reduced the Temperature gradient between Equator and North Pole, thus causing the subtropical jet stream to slow down, making cold air to easily move southward, and thus, more frequent and stronger trough formation in the area .the trough was firstly formed over northeast of the Mediterranean Sea.then moving southward and ...
Acid rain is also a frequent risk produced by lightning. Distilled water has a neutral pH of 7. "Clean" or unpolluted rain has a slightly acidic pH of about 5.2, because carbon dioxide and water in the air react together to form carbonic acid, a weak acid (pH 5.6 in distilled water), but unpolluted rain also contains other chemicals.

Animation: Animation is a method in which figures are manipulated to appear as moving images. In traditional animation, images are drawn or painted by hand on transparent celluloid sheets to be photographed and exhibited on film. Today, most animations are made with computer-generated imagery (CGI).
