Tornadoes

Yes, there are hail storms in the Philippines.

According to the Philippine Atmospheric Seophysical Services Administration (PAG-ASA), a hailstorm occurs when the clouds in the area are too low.

When cumulus and nimbus clouds combine, it produces a solid precipitation, the hail. When the clouds are near the ground, the raindrops which are crystal forms of water could no longer dissolve thus remaining as solid particles when they hit ground.

In a tornado, unlike in other wind storms, air travel upward as well as horizontally. This allows a tornado to lift objects into the air. Sometimes to great heights. Unlike other major wind events, where wind is mostly horizontal, the wind in a tornado has a vertical component as it spirals upward rapidly. This upward-moving wind can carry objects with it.

Tornadoes are classified using the Enhanced Fujita Scale (EF-Scale) based on the estimated wind speed and resulting damage. This scale ranges from EF0 (weakest) to EF5 (strongest), with each rating corresponding to a range of wind speeds and damage potential.

Tornadoes can reach speeds of up to 300 mph (480 km/h), making them one of the fastest wind storms on Earth. The highest wind speeds are typically found in the most intense tornadoes, such as those rated EF4 or EF5 on the Enhanced Fujita Scale.

it is a really hard to earn a living off storm chasing. if you need new camera equipment you spend around 1,000 dollars. you have to pitch in money for hotels and motels when you travel to different states to catch a tornado. you have to drive lots of miles which you end up

Well, first of all, there is warm\hot air moving around and it's a little higher. Cool\cold air does the same thing, but lower. Now that you know that, a tornado occurs when the cool and warm air are moving past each other and then they mix together and spin and build to make a tornado! :-)

The EF or Enhanced Fujita scale is primarily based on damage.

Scientists analyze the damage done by a tornado to estimated what how strong its winds were at peak intensity. The tornado is given the EF rating whose wind range corresponds with the peak wind estimates of the tornado.

Because of the uncertainty of these wind estimates direct win measurements are not used even when they are obtained.

Here are the wind estimate ranges of the Enhanced Fujita scale levels.

EF0: 65-85 mph

EF1: 86-110 mph

EF2: 111-135 mph

EF3: 136-165 mph

EF4: 166-200 mph

EF5: over 200 mph

It depends on the type of waterspout.

Typical waterspouts form by a different mechanism from ordinary tornadoes and are generally weaker. Wind speeds are typically between 40 and 50 mph and rarely exceed 70 mph.

Tornadic waterspouts are ordinary tornadoes that just happen to be on water. They are just as strong as their land based cousins. Wind speeds are usually less than 110 mph, but can, con rare occasions, exceed 300 mph.

The wind of a tornado may be remotely measured using Doppler radar. In rare instances an anemometer makes it inside a tornado and measure wind directly. However, most tornadoes never have their winds actually measured. Instead the wind speed is estimated from the severity of the damage using the parameters of the Enhanced Fujita scale.

According to the NOAA National Hurricane Center, there are an average of 5.8 Atlantic hurricanes per year that affect the United States. Although this doesn't necessarily mean they "hit they US." (See http://www.nhc.noaa.gov/pastprofile.shtml)

In the 2009 hurricane season, there were 2 Atlantic hurricanes.

A Tornado basically looks like a grey cone, but it moves on it's "tip". On top of the tornado, there is usually dark grey clouds. Some tornado's can be skinny and some can be fat. It is usually very, very, very windy when your are somewhere close to the tornado. There may be rain when a tornado is close to your area since tornado's are formed by hot and cold air (ithink..).

Tornadoes vary greatly in intensity and there is in fact a scale that uses the severity of damage to determine intensity. Winds can range anywhere from 65 mph to over 300 mph.

Most tornadoes are rated EF0, with estimated winds of 65 to 85 mph. These tornadoes cause some damage to roofs, gutters, and siding, as well as breaking tree limbs and toppling weakly-rooted trees.

Somewhat fewer tornadoes are rated EF1, with estimated winds of 86 to 110 mph. These tornadoes can badly damage roofs, flip over trailers, and break windows.

Stronger tornadoes are rated EF2, with estimated winds of 111 to 135 mph. These tornadoes tear the roofs from houses, completely destroy trailers and lift cars off the ground.

A small percentage of tornadoes are rated EF3, with estimated winds of 136 to 165 mph. These tornadoes tear down the walls of houses, and uproot most trees, reducing the largest branches to stubs.

About 1% of tornadoes are rated EF4, with estimated winds of 166 to 200 mph. These tornadoes level houses, leaving piles of debris, strip the bark from trees and can even damage road surfaces.

Less that 0.1% of tornadoes are rated EF5 with winds of over 200 mph, sometimes exceeding 300mph. These tornadoes can destroy almost anything. Well-built houses are torn clean off their foundations.

Even two tornadoes of the same rating can cause different amounts of damage, depending on how much of the path experiences the strongest winds. Additionally tornadoes vary in size and how far they travel. A large, and long lived tornado is going to affect a much larger area than a brief, small tornado and probably cause more damage. Where they occur also affects the damage. A tornado that goes over open farmland will cause more damage than one that goes through a city or town.

The weakest wind ever recorded was 0.5 miles per hour (0.2 meters per second). This extremely calm wind speed was measured in several locations around the world during times of unusual atmospheric conditions.

The pressure inside a tornado funnel is lower than the pressure outside. This pressure difference is a key factor in the formation and strength of tornadoes, as the low pressure inside the funnel contributes to the destructive force of the winds associated with tornadoes.

"F" typically stands for the Fujita scale, which is used to measure the intensity of tornadoes based on the damage they cause. The scale ranges from F0 (weakest) to F5 (strongest), with higher ratings indicating more severe damage.

F1 damage is generally describes as moderate.

Typical F1 damage includes broken windows, severely stripped roofs, badly damaged or mostly destroyed trailers, and collapsed garages and porches.

The "F" in tornado classification scales, such as the Fujita scale or the Enhanced Fujita scale, stands for Dr. Tetsuya Theodore Fujita, a Japanese-American meteorologist known for his research on severe convective storms, tornadoes, and microbursts.

A multiple vortex tornado has smaller, short-lived vortices moving around inside of it. The suction vortices have stronger winds than the rest of the tornado and are noted for cutting narrow curved swaths of intense damage. A multiple vortex tornado sometimes has the appearance of two or more tornadoes moving circles.

A single vortex tornado is simply one vortex of tornadic wind.

The same gasses that comprise regular air: nitrogen, oxygen, carbon dioxide, water vapor, and trace amounts of others.

There are three scale that can be used.

The Fujita Scale (F0 to F5) which was used rotate tornadoes in the United States until 2007 and still is used in other countries such as Canada.

The Enhanced Fujita Scale (EF0 to EF5) which uses essentially the same categories as the Fujita scale, only the wind estimates are adjusted and damage analysis is more detailed. It is used primarily in the United States.

The TORRO scale (T0 to T11) uses similar damage and wind estimates to the Fujita scale, but has 2 categories for every 1 on the Fujita Scale. It is primarily used in Britain.

New South Wales (NSW) is the largest state in Australia in terms of area, covering around 809,444 square kilometers. It is home to major cities like Sydney and Newcastle, as well as vast rural and wilderness areas.

The original Beaufort scale was devised by British Admiral Sir Francis Beaufort in the early 19th century to describe wind speed at sea based on its visual effects on ship sails and sea conditions. It has since been modernized to provide a more standardized measurement of wind speed.

It's the other way around; most tornadoes develop in supercells. Like most thunderstorms, supercells develop in an unstable environment with a warm, moist lower atmosphere and a cold upper atmosphere. A lifting mechanism causes a parcel of air to rise to an altitude where it is warmer than its surroundings, and as a result it continues to rise, powered by energy that is released by condensing water vapor. For a supercell the lifting mechanism is usually a cold front or dry line. Wind shear, a condition where wind speed and direction changes with altitude, then sets the storm rotating, giving it the potential to produce tornadoes.

The middle of a tornado is called the "eye." It is a calm and clear area in the center of the storm where winds are at their calmest. The eye is surrounded by the eyewall, where the most intense and destructive winds are found.

Potentially, as the ground level wind speed does not say anything about the potential for a tornado to form. However, you still need to have the right condition brewing up in the storm clouds for one to form.
