Severe Weather 101 A downburst is a strong downdraft that results in an outward burst of damaging winds on or near the ground. Downburst winds may begin as a microburst and spread out over a wider area. [+] A microburst is a small concentrated downburst that produces an outward burst of damaging winds at the surface. Microbursts are generally small (less than 4km across) and short-lived, lasting only 5-10 minutes, with maximum windspeeds up to 168 mph. There are two kinds of microbursts: wet and dry.

Downcasting In Java Downcasting In Java. Upcasting is assigning the sub class reference object to the parent class which is allowed in Java. Downcasting is assigning parent class reference object to the sub class which is not allowed in Java. However, if you do downcasting, there will not be any compiler error.

Karst Topography and Sinkholes The underground water of karst topography carves our impressive channels and caves that are susceptible to collapse from the surface. When enough limestone is eroded from underground, a sinkhole (also called a doline) may develop.arst topography can also be found extensively in the Shan Plateau of China, Nullarbor Region of Australia, the Atlas Mountains of northern Africa, the Appalachian Mountains of the U.S., Belo Horizonte of Brazil, and the Carpathian Basin of Southern Europe.

Sinkhole A sinkhole, also known as a sink, sink-hole, shakehole, swallet, swallow hole, or doline (the different terms for sinkholes are often used interchangeably), is a depression or hole in the ground caused by some form of collapse of the surface layer.

Microburst Tree damage from a downburst. A microburst is a small downdraft that moves in a way opposite to a tornado. Microbursts are found in strong thunderstorms. There are two types of microbursts within a thunderstorm: wet microbursts and dry microbursts. They go through three stages in their cycle, the downburst, outburst, and cushion stages.

Earth Science Exam 4 10/ Upwelling, the rising of cold water from deeper layers to replace warmer surface water, is a common wind induced vertical movement. Coastal upwelling occurs in areas where winds blow towards to equator and parallel to the coast.

- Downdraft carburetors fall into two types, one the unbalanced type and the other a balanced type unit. In the bowl cover of the unbalanced type carburetor, is a hole drilled to a definite dimension. It is through this hole that air flows and exerts pressure, or pushes against the gasoline in the float bowl.

- A downburst is a strong downdraft which includes an outburst of potentially damaging winds on or near the ground. If the diameter of the downburst is less than 2.5 miles, it is called a microburst. The diagrams below depict the evolution of a microburst.

Karst Topography - Teacher's Guide and Paper Model Our paper model shows features normally associated with karst topography. Sinkholes (also known as dolines) are surface depressions formed by either: 1) the dissolution of bedrock forming a bowl-shaped depression, or 2) the collapse of shallow caves that were formed by dissolution of the bedrock.ermeable bedrock makes a good aquifer, a rock layer that holds and conducts water. If the ground water that flows through the underlying permeable bedrock is acidic and the bedrock is soluble, a distinctive type of topography, karst topography, can be created.

Design and Construction of Screened Wells for Agricultural Irrigation Systems 1 The depth by which the water level is lowered below the static level in a well when pumping is in progress is called drawdown. Drawdown is the difference, measured in feet of water, between the static water level and the water level during pumping.

Sinkhole Print Email. A sinkhole, also known as a sink-hole, sink, swallow hole, shakehole, swallet or doline, is a natural depression or hole in the Earth's surface which may have various causes. Some are caused by karst processes—for example, the chemical dissolution of carbonate rocks or suffosion processes in sandstone.

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.

List of karst areas From Wikipedia, the free encyclopedia. Karst topography is a geological formation by the dissolution of a layer or layers of soluble bedrock, usually carbonate rock such as limestone or dolomite, but also in gypsum.It has also been documented for weathering-resistant rocks, such as quartzite, given the right conditions.rom Wikipedia, the free encyclopedia.

Down feather The word down comes from the Old Norse word dúnn, which had the same meaning as its modern equivalent. The down feather is considered to be the simplest of all feather types. It has a short or vestigial rachis (shaft), few barbs, and barbules that lack hooks.

Sunburst A sunburst is a design or figure commonly used in architectural ornaments and design patterns. It consists of rays or beams radiating out from a central disk in the manner of sunbeams. Sometimes part of a sunburst, a semicircular or semi-elliptical shape, is used.

- A debris slide is a small sudden downstope movement of unconsolidated material. This type of slide produces a hummocky surface of low relief. A mudflow is a mass of saturated rock particles of all sizes. This type of landslide is caused by a sudden flood of water from a cloudburst in semi-arid country or a sudden thaw. The flood waters carry the soil and rocks from a large slope area and washes them to a gulch or canyon.

Microbursts Introduction: 1  Microbursts are small scale, intense local downdrafts which, on reaching the surface, spread outward in all directions from the downdraft center. 2  This causes the presence of both vertical and horizontal wind shears that can be extremely hazardous to all types and categories of aircraft, especially at low altitudes.

What is a 'Drawdown' What is a 'Drawdown'. A drawdown is the peak-to-trough decline during a specific recorded period of an investment, fund or commodity. A drawdown is usually quoted as the percentage between the peak and the subsequent trough. Those tracking the entity measure from the time a retrenchment begins to when it reaches a new high.

Downburst To differentiate between tornado damage and damage from a downburst, the term straight-line winds is applied to damage from microbursts. Downbursts are particularly strong downdrafts from thunderstorms.ften producing damaging winds, it may be confused with a tornado, but is different in that a tornado, high velocity winds circle a central area, moves inward and upward whereas in a downburst, winds are directed downward and then outward from the surface landing point.

- Cover-Collapse Sinkholes. A geologic hazard is a naturally occurring geologic condition that may result in property damage or may be a threat to the safety of people. The geologic hazards associated with karst are: sinkhole flooding, groundwater vulnerability, radon, and cover-collapse sinkholes described on this page.

- 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.

- Quick Answer. According to Business Dictionary, a loan drawdown is when someone withdraws funds from a loan facility. Practical Law says lenders often allow drawdowns to give money advances to borrowers and set interest rates based on these short borrowing periods.
