Hurricanes

http://www.comet.ucar.edu/nsflab/web/hurricane/311.htm

A hurricane is an intense, rotating oceanic weather system that has fast moving winds moving more than 119 km/hr (74 mph). It forms and gets stronger over tropical oceanic regions. Hurricanes are usually smaller than storms in mid-latitudes, about 500 km (311 miles) in diameter.

The factors for starting a hurricane include an already existing weather disturbance, warm tropical oceans, moisture, and relatively light winds. If the right conditions continue long enough, they can combine to produce the violent winds, incredible waves, pouring rains, and floods could also occur.

Cyclones

Cyclones are strong spiraling storms caused by winds rising from a low atmospheric pressure. Strong winds along with heavy down pour are parts of a cyclone. Cyclones in the northern hemispheres blowing in anti-clock wise direction are known as hurricanes or typhoons. The tropical storms blowing in the southern hemisphere are known as cyclones and here the winds blow in a clockwise direction and inwards.

A cyclone starts when air near the equator becomes over-heated and rises quickly creating low-pressure areas. As the hot air rises, it becomes overloaded with moisture. The moisture in the air condenses to produce thunderclouds. When the warm air rises, it creates a vacuum. The cool air gushes into this empty space and later spirals upward with huge force. The reason for spiraling of the air is because of the constant rotation of the earth on its own axis. The wind spirals faster as it moves upwards creating a huge circle that can span up to 2,000 kilometers.

HOW WIND ENERGY IS PRODUCED

Wind is air in motion. It is caused by the uneven heating of the Earth's surface by the sun. During the day, the air above the land heats up more quickly than the air over water because water has a high specific heat. During the day, the air over the land is warmest and least dense, and the cooler, denser air over the water goes towards the land, creating wind. At night, the air over the water is warmest and least dense, and the cooler, denser air over the land goes towards the water, also creating wind. So if you live in a coastal region and got a wind turbine, it would not only save your money, but the environment as well. In the same way, the winds that circle the Earth are created because the land near the Earth's equator is heated more by the sun than the land near the North and South Poles.

TECHNOLOGY & HOW IT IS PRODUCED

Wind turbines use blades to collect the wind’s kinetic energy. The wind flows over the blades creating lift, like the effect on airplane wings, which causes them to turn. The blades are connected to a drive shaft that turns an electric generator to produce electricity.

Wind generation is becoming more common in the United States. Generation from wind in the United States nearly doubled between 2006 and 2008.

POSITIVE ASPECTS

You could get a wind turbine installed outside your house. It will produce energy as long as the sun is available. Even on a cloudy, sunless day, there is still wind blowing, so that means it would produce energy in the winter. Today, wind energy is mainly used to generate electricity. Wind is a renewable energy source because the wind will blow as long as the sun is available.

LIMITATIONS & DRAWBACKS

If you don't live in a coastal region, you could only get the wind created from the Equator and the Poles, and not get the faster, more powerful wind from the Land and Sea Breezes.

% OF ENERGY PRODUCED

In 2008, wind turbines in the United States generated a total of 52 billion kilowatthours, about 1.3% of total U.S. electricity generation. Even though this is a small percentage of the Nation's total electricity production, it was enough electricity to serve 4.6 million households or to power the entire State of Colorado.

The amount of electricity generated from wind has been growing very fast in the recent years. Generation from wind in the United States nearly doubled between 2006 and 2008.

This could be the new way of living in the future. “Green Ark” designed by Russian architect Alexander Remizov, said this building has transparent solar panel to house energy and if it is put on water, it can use the thermal energy from the water. It can be built to house 50 people to 10,000 people.

1) Name 2 ways that the energy bubbles could have formed?

2) What was the energy bubbles definitely not caused by?

3) How do the scientists know that the energy bubbles were not caused by this?

PICTURE OF A LENTICULAR CLOUD

I think that aliens cannot be real because we should have proof that there are, or we probably could also see them in space with all the satellites monitoring everything on Earth, but not space. The people who really think that aliens are real should team up with a space team/company and set up some satellites in space to monitor the things going in and out of the Earth. Also, if aliens are real, why would they be coming to Earth for no apparent reason? If they wanted something, then they would probably take it and if they killed humans, then there would be police reports and investigations. I think that the photograph taken on the website was a Lenticular Cloud. To prove my theories, this is a picture of a Lenticular Cloud, commonly mistaken for U.F.O.’s.

I think that other life sustaining planets are very real because scientists actually HAVE PROOF that Mars once had water, unlike theories that aliens are or aren’t real. And when I say that the life sustaining planets can have or had non-earthlike life forms, I dont mean 6 feet tall, glowing green/white, egg head aliens, I mean like small types of fish or bacteria. I believe this life form once lived in the waters of Mars.
