Tornadogenesis. A sequence of images showing the birth of a supercellular tornado. First, the rain-free cloud base lowers as a rotating wall cloud. This lowering concentrates into a funnel cloud, which continues descending simultaneously as a circulation builds near the surface, kicking up dust and other debris.
Geomagnetically induced currents (GIC) are electrical currents induced at the Earth's surface by rapid changes in the geomagnetic field caused by space weather events. GICs can affect the normal operation of long electrical conductor systems such as electric transmission grids and buried pipelines. The geomagnetic disturbances which induce GICs ...
A geomagnetic storm, also known as a magnetic storm, is a temporary disturbance of the Earth 's magnetosphere caused by a solar wind shock wave. The disturbance that drives the magnetic storm may be a solar coronal mass ejection (CME) or (much less severely) a co-rotating interaction region (CIR), a high-speed stream of solar wind originating ...
This includes a description word for each level of the scale. The Enhanced Fujita scale (abbreviated as EF-Scale) rates tornado intensity based on the severity of the damage they cause. It is used in some countries, including the United States and France. [1] The EF scale is also unofficially used in other countries, including China.
As the tornado lofted debris at significant wind speeds across the vehicle, the storm chasers' ears popped from the significant pressure change. Then, in a matter of seconds, it was over.
A tornado is a violently rotating column of air that is in contact with both the surface of the Earth and a cumulonimbus cloud or, in rare cases, the base of a cumulus cloud. It is often referred to as a twister, whirlwind or cyclone, [ 1 ] although the word cyclone is used in meteorology to name a weather system with a low-pressure area in the ...
A powerful storm tore through Garner, N.C., Sunday afternoon, Dec. 10, 2023. The NWS confirmed that an EF-1 tornado, with peak winds at 110 mph, did hit Garner between 12:28 and 12:32 p.m.
On May 27, 1997, an extremely violent and destructive multi-vortex tornado struck the community of Jarrell, Texas, killing 27 people and injuring a further 12. [1] The tornado caused $40.1 million (1997 USD) in damages and was the subject of multiple well-known photographs, earning the tornado the nickname of the "Dead Man Walking ".
