What are the three factors that weaken a hurricane during development?
Three factors that weaken a hurricane during development are wind shear, cooler sea surface temperatures, and dry air intrusions. Wind shear disrupts the organization of the storm, cooler sea surface temperatures reduce the heat and energy available for the storm, and dry air can inhibit thunderstorm activity needed for hurricane development.
What is the steps that change wind shear into a tornado?
When wind shear occurs, air moves at different speeds, heights, and directions. This can eventually lead to the formation of a mesocyclone. A mesocyclone is a rotation column of air, starting at horizontal, but becoming vertical when a powerful updraft knocks it vertical. If a RFD is present, it will rotate downward hugging the surface of the mesocyclone, funneling a smaller and smaller point as it reaches the bottom. This is like a skater pulling in her arms, leading to faster rotation. The same is true for tornadoes. If a powerful updraft creates a low pressure area near the surface, the combination of RFD pushing downward and low pressure area near the surface, drawing the funnel downward, could eventually lead to a complete tornado.
Causes columns of clouds to spin and may form a funnel cloud?
The rotation in a thunderstorm that produces a tornado comes from wind shear, a difference in wind speed and direction with altitude. In the systems that produce tornadoes in the northern hemisphere, you will typically find lower level winds coming out of the west with winds higher up coming out of the south. A counterclockwise change in direction. This creates a counterclockwise circulation in the thunderstorm that can produce a tornado. In the Southern Hemisphere the upper level winds are out of the north and clockwise rotation results.
What must happen for a tornado to form?
The formation of tornadoes is complicated.First, a condition called wind shear, in which the speed or direction of the wind changes with altitude. If the shear is strong enough it can essentially tilt a thunderstorm, this separates the updraft and downdraft of the thunderstorm, preventing them from interfering with one another. This allows the storm to become stronger and last longer.Additionally, if the wind shear is strong enough it can start the air rolling in what is called horizontal vorticity. This horizontal vorticity can then be turned vertical by a thunderstorm's updraft. When this happens, the thunderstorm may start rotating. The rotation is especially strong in an updraft called a mesocyclone. If the storm intensifies rapidly enough, a relatively warm downdraft called a rear-flank downdraft or RFD can wrap around the bottom part of the mesocyclone. This can then tighten and intensify its rotation and bring it down to the ground to produce a tornado.
Why do tornadoes go counter clockwise?
Fort the most part that is limited to tornadoes in the northern hemisphere. Nearly all southern hemisphere tornadoes rotate clockwise. Tornadoes are formed from thunderstorms called supercells, and get their counterclockwise rotation from the rotation in those storms. The storms get their rotation from wind shear, or differences in wind speed and direction with altitude. In the northern hemisphere the wind shear is usually counterclockwise with increasing altitude. For example the wind at ground level may be out of the west while higher up it is out of the south, so it shifts in a counterclockwise manner. This can impart a counterclockwise spin on the updraft, or rising air current of a thunderstorm.
Why do tornadoes spin counterclockwise in the northern hemisphere?
In the northern hemisphere, wind shear usually works so that wind direction turns counterclockwise with increasing altitude, so for example, at ground level the wind may be out of the west while higher up it may be out of the south. If the wind shear is strong enough it can impart a counterclockwise rotation on the updraft of a thunderstorm. This rotation will then be passed on to any tornado the storm produces.
What wind may have gusts that come from various directions?
Wind shear is when wind changes speed and direction over a small distance. Strong wind shears can help form tornadoes and hail and can cause turbulence in airplanes.
Which one of the cause a tornado stationary fronts or wind shear condensation dry climates?
Condensation and wind shear are both important in tornado formation. Tornadoes develop from thunderstorms, which are powered by the energy released from condensation. Wind shear is what gives thunderstorms the rotation then need to produce tornadoes. Tornado-producing storms may form along a stationary front, but are more common along cold fronts.
Why do tornadoes from more often between February and April?
Tornadoes are more common in April, May, and June than in February or March. The two most fundamental ingredients needed for making tornadoes are instability and wind shear. Instability occurs when the lower atmosphere is warm and moist and cools quickly with increasing height. Instability allows thunderstorms to form. Wind shear occurs when the speed and direction of wind changes with altitude. Wind shear tends to be strongest in winter and weakest in summer, while the opposite is true of instability. The most ideal combination of wind shear and instability generally occurs in the spring.

Wind shear disrupts the organization of the storm, cooler sea surface temperatures reduce the heat and energy available for the storm, and dry air can inhibit thunderstorm activity needed for hurricane development.
What are hospital's involvement in hazardous materials and events?
Hospitals may use hazardous materials in their cleaning and maintenance operations, in their pharmacies, and some patient treatment procedures. They are also involved with hazardous materials if an emergency patient is brought in who may have been exposed to a hazardous material or may be contaminated with a hazardous material.
How do bridges withstand external forces?
tension pulls on the bridge, compression acts upon the supports of the bridge, and shear is created because of the wind blowing on the wind. extreme weather or earthquakes may cause torsion, but it's very rare that you'll find that in a bridge.

What are three factors that weaken a hurricane during development?
Many factors may cause the development of a hurricane to weaken. Three factors are low sea surface temperature, high wind shear and making landfall.
Is lube oil considered a hazardous material?
Depending on what it has been lubricating and where, used lubricating oil may be a hazardous materials. Specially formulated lubricants may also be hazardous if used improperly or carelessly.
Is it correct to say shear tensile strength or tensile shear strength?
The correct term is "shear tensile strength." This term refers to the material's ability to withstand shear stresses before failure, particularly in situations where tensile forces are also acting. "Tensile shear strength" is less commonly used and may cause confusion, as it implies a different relationship between tensile and shear stresses.
How do detect a microburst?
Microbursts can be detected using weather radar. A sudden and intense downward air current can cause a radar signature called a radar wind shear pattern. Pilots may also detect a microburst while in flight due to sudden changes in airspeed, altitude, and wind direction.
