He believed that fire and water opposed each other in the atmosphere, and when fire gained the upper hand, the result was summer, and when water did, it was winter. Democritus also wrote about the flooding of the Nile. He said that during the summer solstice, snow in northern parts of the world melted.
Snow occurs when the atmosphere is "cold" all the way from the clouds to down here at the surface. And rain occurs when it's "warm" all the way from the clouds to the surface.
The Earth's atmosphere is the origin of the weather phenomena studied in meteorology. Atmospheric composition, temperature, and pressure vary across a series of distinct sublayers including the troposphere and stratosphere. The properties of Earth's atmosphere vary by altitude across a series of distinct layers. atmospheric boundary layer (ABL)
Atmospheric convection is the vertical transport of heat and moisture in the atmosphere.It occurs when warmer, less dense air rises, while cooler, denser air sinks. This process is driven by parcel-environment instability, meaning that a "parcel" of air is warmer and less dense than the surrounding environment at the same altitude.
A "Pineapple Express" weather system, or atmospheric river storm, moves towards the U.S. west coast in a composite image from the National Oceanic and Atmospheric Administration (NOAA) GOES-West ...
Severe weather can occur under a variety of situations, but three characteristics are generally needed: a temperature or moisture boundary, moisture, and (in the event of severe, precipitation-based events) instability in the atmosphere.
Snow can be compacted to form a snow road and be part of a winter road route for vehicles to access isolated communities or construction projects during the winter. [78] Snow can also be used to provide the supporting structure and surface for a runway, as with the Phoenix Airfield in Antarctica. The snow-compacted runway is designed to ...
The phenomenon, known as thundersnow, occurs when a thunderstorm produces snow instead of rain. The weather event is so rare that Weather Channel meteorologist Jim Cantore can barely contain his ...
