- ... and consequently produces heavy rainfall. When the hurricane reaches its maturity an eye develops in the centre, in the eye there is a relative area of subsiding pressure. Which is what causes clear skies, anomalous high temperatures and light winds. Eventually the eye disappears as a result of the descending air increasing instability, which in turn warms and increases the storms intensity. Around the eye there are towering Cumulo-nimbus clouds ...

- ... favour hurricane formations such as Hurricane Gilbert. The sea surface temperatures were in excess of 30ēC. There were no strong inversions which would prevent the growth of deep clouds- convectively unstable air. There was a high relative humidity in the middle troposphere. There was little change of the horizontal wind with increasing height (low vertical wind shear). An existing cyclonic rotation of the winds in the lower troposphere is also a ...

- ... a week or more (example: Hurricane Dorthy) In that time, it may travel tens of thousands of miles over the sea and land. At sea, hurricane winds whip up giant waves up to 20 feet high.

The proto-gorilla was then isolated in high mountain areas, which forced it to become a herbivore. It also became larger than its fellow apes to contend with the cold temperatures of its environment. The gorilla, hence, came to be what it is ...

- 6947: How Dams Affect Salmon Migration
- ... investigated for their potential for guiding downstream migrants into unsafe bypasses, using, for example, noises, oxygen bubbles, lights, louvers, and screens. The costs of the installation and their indifferent success has discouraged the notion that high or large dams can be reconciled with salmon production. The Colombia River system is stitched with hydroelectric dams that produce the countries cheapest power, 40 percent cheaper than the national average. This cheap electricity is ...

- ... air freighted by C-5A to Edwards AFB on January 8, 1974. It was an unintended short hop around the pattern on January 21, 1974 at the hands of the test pilot Phil Oestricher. During high-speed ground tests at Edwards, Oestricher had inadvertently scraped the tailplane on the runway as the nose was raised, and a violent lateral oscillation set in. he decided to take off and regain control in ...
