What is a microburst? There are a handful of factors that cause microbursts to develop, including mid-level dry air entrainment, cooling beneath the thunderstorm cloud base, sublimation (occurs when the cloud base is above the freezing level), and the existence of rain and/or hail within the thunderstorm (i.e. precipitation loading).

What causes a crevasse on glaciers? A quick or sharp movement from the glacier could cause the crevasse. Fast increases in temperature or the overall global warming can cause the glaciers to form crevasses as well. Also in some cases water flows can cause or deepen crevasses.

- A weather phenomenon, called a microburst, may cause destruction just as devastating as a tornado does. A microburst is a small column of exceptionally intense and localized sinking air that results in a violent outrush of air at the ground.

Pneumonia 1 Bronchopneumonia causes scattered, patchy infiltrates of inflammation in the air sacs throughout the lungs. 2  It is more diffuse than lobar pneumonia. 3  Lobar pneumonia causes an inflammation of one lobe of a lung and typically involves all the airspaces in a single lobe.

- A cloudburst is essentially an extremely heavy downpour that is defined as rainfall rate >=100 mm /hour. Some reasons for occurrence of cloudbursts are: When a cloud encounters a mountain or such physical body in its path causing it to shed its entire moisture-load in a small span of time. In a thunderstorm, air currents carrying huge amounts of water rush upwards. If they cease, the entire amount of water carried by these air currents descends upon a small area.

Microbursts The hazard occurs principally when the spatial scale of the downburst is on the order of a runway length. Because of the importance of this scale, Fujita (1985) defined a microburst as a downburst that extends no more than 4 km (2.2 n mi) over the surface.

The Why Files Earth is not always as solid as a rock. In large parts of Florida and other states, a soluble subsurface geology called karst is conducive to sinkholes. Karst occurs in rock dominated by gypsum, limestone or salt — which can dissolve, leaving underground streams and cavities.

Why does my engine spit or backfire? Backfiring through the carb (spitting or coughing) usually occurs in the morning when a carb's air/fuel mixture is a bit too lean. This usually goes away once the engine warms-up. It is also commonly caused by the accelerator pump inthe carb not squirting enough fuel before the main jets start working.ackfiring through the carb (spitting or coughing) usually occurs in the morning when a carb's air/fuel mixture is a bit too lean.

River Bank Erosion Causes of River Bank Erosion. River Bank erosion has several causes with even more factors that can accelerate it. The major causes are flooding, land use, stream management, over-clearing of catchment and stream bank vegetation, and poorly managed sand and gravel extraction. Factors That Accelerate Erosion: Stream bed lowering or in fill

List of sinkholes List of sinkholes. The following is a list of sinkholes, blue holes, dolines, cenotes, and pit caves. A sinkhole is a depression or hole in the ground caused by some form of collapse of the surface layer. Some are caused by karst processes—for example, the chemical dissolution of carbonate rocks or suffosion processes.

- A microburst is a sudden and intense downdraft within a severe thunderstorm that produces powerful winds. Unlike a tornado the winds in a microburst travel downward and outward and do not rotate. 8 people found this useful.

- Top 10 amazing movie makeup transformations. Thunder is caused by the sudden expansion of the air around a lightning bolt's path. The deep rumbling and sharp cracks of thunder are produced as the air around the lightning bolt is superheated — up to about 54,000° Fahrenheit (about 33,000° Celsius) — and rapidly expands.

- A carbuncle is a cluster of boils, draining pus onto the skin. It is usually caused by bacterial infection, most commonly with Staphylococcus aureus or Streptococcus pyogenes, which can turn lethal. However, the presence of a carbuncle is actually a sign that the immune system is working. carbuncle is a cluster of boils, draining pus onto the skin.

Foundation Engineering Problems and Hazards in Karst     Terranes In some karst terranes, collapse sinkholes form when the roof of a cave or cavern collapses. Such is the case in some collapses in Florida (Sinclair, 1982). However, most collapse sinkholes seem associated with cavities in the soil overlying the carbonate rock.

What causes tornadoes? As the mesocyclone lowers below the cloud base, it begins to take in cool, moist air from the downdraft region of the storm. This convergence of warm air in the updraft, and this cool air, causes a rotating wall cloud to form.

What is a microburst? A microburst is a downdraft (sinking air) in a thunderstorm that is less than 2.5 miles in scale. Although microbursts are not as widely recognized as tornadoes, they can cause comparable, and in some cases, worse damage than some tornadoes produce.

Technical Guide to Mine Subsidence Sinkhole subsidence is common in areas overlying shallow room-and-pillar mines. Sinkholes occur from the collapse of the mine roof into a mine opening, resulting in caving of the overlying strata and an abrupt depression in the ground surface.

- Nobody knows exactly what causes tornadoes, but they form in powerful storms, usually thunderstorms although other storms have been known to create them. Tornadoes are too small to be created by the Coriolis effect, which is what causes the spin in most weather systems.

- What is cloud burst? A cloudburst is sudden copious rainfall. It is a sudden aggressive rainstorm falling for a short period of time limited to a small geographical area. Meteorologists say the rain from a cloudburst is usually of the shower type with a fall rate equal to or greater than 100 mm (4.94 inches) per hour. Generally cloudbursts are associated with thunderstorms. The air currents rushing upwards in a rainstorm hold up a large amount of water.

- These are all the seismic waves that the seismograph has recorded. Most of these waves were so small that nobody felt them. These tiny microseisms can be caused by heavy traffic near the seismograph, waves hitting a beach, the wind, and any number of other ordinary things that cause some shaking of the seismograph.ost of these waves were so small that nobody felt them.

Sinkholes: The Human Impact Collapse sinkholes are rare, forming in landscapes that have developed over several thousands or millions of years. Of the three types, sinkholes formed in the soil overburden are far more common and have presented a serious geohazard (a geologic phenomenon with widespread damage potential) in karst regions. Cover-subsidence sinkholes are made by suffusion, a process wherein unconsolidated soil washes down into open fissures and caves in the underlying bedrock and the land surface above gradually sinks.
