  • Air Swirls Around A Tornado Center

    Hurricanes get their start over the warm tropical waters of the North Atlantic Ocean near the equator. Most hurricanes appear in late summer or early fall, when sea temperatures are at their highest. The warm waters heats the air above it, and the updrafts of warm, moist air begin to rise. Day after day the fluffy cumuli form atop the updrafts. But the cloud tops rarely rise higher than about 6,000 feet. At that height in the tropics, there is usually a layer of warm, dry air that acts like an i...

    INTRODUCTION - Since its introduction to the New Jersey shore in 1988, the western Pacific shore crab Hemigrapsus sanguineus has spread to inhabit rocky intertidal locations along the Atlantic coast from Massachusetts to North Carolina (McDermott 1998).

  • Water Nears The Boiling Point
    363 words
    I went online and found out a lot of information about boiling water. If you cover the tin and allow the water and air to cool down, the air will cool and contract, lowering the pressure in the tin. If it lowers enough, the partial vacuum will collapse the walls of the can! The boiling point definitely reduces with air pressure. There is a famous demonstration where boiling water or coffee is drunk, the trick is it was in a vacuum chamber where it boiled at room temperature. The actual definitio...

  • Lightning And Hail Thunderstorms
    1,727 words
    Formation of Thunderstorms, Lightning, Hail and Blizzards Thunderstorms Thunderstorms are formed when temperature imbalances are present in the atmosphere. They are a violent example of convection. The warming of the air near the earth and / or the cooling of the air above puts the warmer lighter layers below the colder denser layers. This causes instability and convection overturns the layers. The colder, denser air sinks below the warmer lighter air which is rising rapidly. The same conditions...
