What Are Thunderstorms? - Definition, Types & …

Thunderstorms are formed by the uplifting of warm and humid air. There are many factors that lead to the uplifting of air, for example, solar heating; in the vicinity of low pressure troughs; when two different air streams meet; or when air is forced uphill.

The participants of the workshop identified several specific questions related to interactions among large-scale environment (shear, moisture, surface conditions), cold pool dynamics, updraft/downdrafts, microphysical (especially ice) process, and their representation in the next generation climate models. They proposed a set of short-term and long-term integrated observing and modeling strategies to address them. A report on the outcome of the workshop is being prepared and .

ASR principal investigators are an important user group for the ARM Facility, contributing 75 percent of scientific publications resulting from ARM data.

Thunderstorms occur mainly in spring and summer. They are characterized by flashes of lightning and rumbles of thunder.

Because it is very turbulent inside a cumulonimbus cloud, the water droplets and ice crystals in it will break up and become electrically charged. Generally speaking, the upper portion of the cloud is positively charged, while the middle and lower portions are negatively charged. When the electric voltage between the positive and negative charges is large enough, discharges take place between clouds or between cloud and the earth's surface, and lightning is said to have occurred. The electric current in a lightning discharge generates a large amount of heat. This causes a very rapid expansion of the local air, resulting in rumbles of thunder.

Earthquakes are not only measured on Richter scale but also on the scale of personal loss. . The deadliest earthquake recorded in history was on January 23, 1556 in Shaanxi, China. It devastated around 520 miles of area and resulted in more than 20 meters deep crevices and landslides, which collapsed numerous dwellings. The death toll of this devastating calamity was 830,000, which is over 60% of the region’s population though its magnitude was only 8.0 on the Richter scale. Earthquakes strike suddenly, violently and usually without warning. It is impossible to determine their true potential before they strike; hence the extent of damage they can cause is highly unpredictable. Identifying potential hazards before time and planning in advance can reduce the dangers of loss of life and property from an earthquake. Depending upon its magnitude it can cause other catastrophes like Tsunami, Volcanic eruptions, Landslides, Fires etc. Though earthquakes aren’t deadly, the aftermaths are. Sometimes earthquakes are actually fore-shocks and an indication that a larger earthquake might occur.

This biome occurs along the Pacific Northwest coast of North America where annual precipitation is high and temperatures are mild.

Thunderstorms are common all over the world

There can be as many as 40,000 thunderstorms each day around the world. They are most common in the U.S., where they can produce tornadoes, floods, lightning and damaging winds.

The researchers found that even weak and marginally electrified storms are capable of producing TGFs.

How are lightning and thunder produced

NSSL's On-Demand web-based tool helps confirm when and where severe weather occurred by mapping circulations or hail detected by radar on Google Earth satellite images. NWS forecasters can quickly review warnings and check their accuracy with this system. Emergency responders and damage surveyors have also used On-Demand to produce high-resolution street maps of affected areas, so they can more effectively begin rescue and recovery efforts and damage assessments.

Straight-line winds are responsible for most thunderstorm damage. These winds can cause as much damage as a tornado.

If you see the water recede quickly and unexpectedly from a beach or if you are on the coast and there is an earthquake ,run toward higher ground or inland—there may be a tsunami coming. This is another natural disaster claiming the lives of thousands of people. It has devastated countries such as Haiti, Indonesia, China, and the United States. Tsunami is regarded as the most horrific disasters of all times. About 80% of tsunamis occur in the Pacific Ocean, but they can occur anywhere from oceans, seas to even lakes. They are caused by underwater earthquakes, landslides, volcanic explosions and glacier calving. The 2004 Indian Ocean earthquake, which had a magnitude of 9.3, triggered a series of lethal tsunamis on December 26, 2004, killing approximately 230,210 people, making it the deadliest tsunami in recorded history.
