No, they are not some super successful people or any genre of Hollywood stars. They are the names of hurricanes. Sounds familiar? Do you know what is a hurricane?
Hurricane is a tropical cyclone with a speed of around 74 miles per hour characterized with heavy rains and winds. This is the result of low pressure system that is usually created around tropical areas. They are a part of the natural circulation system that moves heat from the tropical regions to the places of higher altitudes.
Hurricanes are known by several names in different continents of the world. In the North Atlantic and South Atlantic region Hurricane is the official term used for tropical cyclone. The other parts of world in Northwest Pacific Ocean name hurricane as Typhoon. The hurricanes are called severe cyclonic storm in the north Indian Ocean.
All these nomenclatures refer to the similar phenomenon of low pressure in tropical areas. The only difference between a hurricane and cyclone is that cyclone is any low pressure atmospheric activity in the southern hemisphere. Where, hurricane is an atmospheric activity with in the northern hemisphere of the globe.
Hurricanes are also called the reverse heat engines. Reason being, they happen due to the condensation of water around the tropical regions. The condensation or rising water vapors in air cause a series of reaction to trigger on the hurricane. As the air heats up around the warm ocean, the water becomes even warmer. As a result the air moves towards the ground with heavy thunders carrying the ocean water with it.
After knowing what is a hurricane, you will be even more amazed to know the power of a hurricane. A hurricane releases heat at the rate of fifty to two hundred trillion watts every twenty minutes. This energy is equivalent to the explosion of ten megaton nuclear bomb exploded every twenty minutes.
The hurricanes are divided into five categories according to their effects. Category one has the weakest winds. A hurricane above the wind speed of 67 miles per second is a category five hurricane.
There are certain factors that form a hurricane. The primary factor towards the formation of hurricane is temperature. The sea level temperature more than 26.5 degrees up to a depth of 50 meters is a sign of worry. The warm water or the water vapors are a major source of hurricane occurrence. Low temperature is actually conductive for hurricane formation.
Hurricanes are predictable when temperatures are the highest. Consequently, different continents will be having dissimilar months for the highest possibility of a hurricane formation. North Atlantic has witnessed 217 hurricanes in the month of September since 1944 till date. The peak time for hurricane arrival in the North Indian Ocean is April to December.
Millions of years ago the ancient oceans had microorganisms that lived and died in the oceans. When the microorganisms died there bodies fell to the ocean floor. After the bodies decomposed, what was left was almost pure carbon. The crust of the earth surface is in constant motion. Movement is due to tectonic plates and the continental drift.
When one of the tectonic plates was pushed under another the bodies of the microorganism, now carbon, is also buried under tons of rock. The carbon is subject to extreme pressures by the rock pressing down upon it and by extreme heat, which is usually between 1100, and 1400 degrees Celsius. If the carbon being acted upon is pure then the diamond will be colorless which is normal for diamonds. If nitrogen or sulphur is also included in the carbon then some color may be added to the diamond.
This process preserves the unique crystal structure that makes diamonds the hardest natural material known. The arrangement of the atoms causes the diamonds to have tighter atoms than any other substance in the world. When volcanoes erupted, every once in a while, the microorganisms, which are now diamonds, are forced to the service. Conventional diamonds are mined from explosive volcanic rocks (kimberlites) that transport them from depths in excess of 100 kilometers by volcanic action.
Man Made.
In the year 2004, scientists from Carnegie Institution's Geophysical Laboratory managed to produce gems that are harder than any other crystals. These man made diamonds were produced using a gas mixture. The crystals that were produced were so hard that the instruments and paraphernalia used to make them broke. The great part about these man made diamonds is they were created in less than a day.
Put pure carbon under enough heat and pressure, about 2,200 degrees Fahrenheit and 50,000 atmospheres and it will crystallize into the hardest material known. That is a very simplistic view and also very hard to do. Modern methods use a very complicated process that requires the crystals to be grown using a special high growth-rate chemical vapor deposition. Then the crystals were exposed to very high pressure and temperatures make them harder. There is then a production of a chemical reaction that yields what is called carbon rain. The carbon rain atoms arrange themselves in the same structure as the container or seed used to catch the carbon rain. As they arrange themselves into a tight composition, they turn into man-made diamonds.
Most of the man made diamonds are yellow in color. This is due to the chemicals used in the creation process. Man-made diamonds are very difficult to distinguish from natural ones. A trained jeweler could tell the difference if he could detect the different growth patterns and the lack of inclusions. Inclusions are the tiny bits of material that are usually imbedded in a natural diamond and are considered a flaw.
