An earthquake is caused by a sudden slip on a fault. Tectonic plates are always slowly moving, but they can get stuck at their edges due to friction.When the stress on the edge of a tectonic plate overcomes the friction, there is an earthquake that releases energy in waves that travel through the Earth's crust and cause the shaking that is felt.
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.
Hurricane Floyd was a destructive hurricane that hit North Carolina and New Jersey during the 1999 Atlantic hurricane season. The image above was taken of Floyd near its peak intensity, and because the image is so striking, it has often been attributed to other, more recent destructive storms such as Hurricane Jeanne and Hurricane Katrina .
Due to this, weather patterns can experience some variation, and so extreme weather can be attributed, at least in part, to the natural climate variability that exists on Earth. Climatic phenomena such as the El Niño-Southern Oscillation (ENSO) or the North Atlantic Oscillation (NAO) impact weather patterns in specific regions of the world ...
Hurricane Milton slammed into Florida's Gulf Coast Wednesday night, packing 120 mph winds as a Category 3 storm and bringing a new wave of destruction to an area already reeling from the ravages ...
Within the Dvorak satellite strength estimate for tropical cyclones, there are several visual patterns that a cyclone may take on which define the upper and lower bounds on its intensity. The central dense overcast (CDO) pattern is one of those patterns. The central dense overcast utilizes the size of the CDO.
Fairly soon, though, after Sept. 10, several weather patterns start to interrupt the ability of tropical storms and hurricanes to form. First, air temperatures begin to decline, and cold fronts ...
Common developmental patterns seen during tropical cyclone development, and their Dvorak-assigned intensities. The Dvorak technique (developed between 1969 and 1984 by Vernon Dvorak) is a widely used system to estimate tropical cyclone intensity (which includes tropical depression, tropical storm, and hurricane/typhoon/intense tropical cyclone intensities) based solely on visible and infrared ...
