Chapter 1IntroductionBackground and importance The hurricanes that occurred in the country, Thai might cause more damage, but the domestic Thai has not yet caused any hurricanes. Origin or the area of tropical hurricanes occurred. Tropical hurricanes are common words that are used to call the hurricane or cyclone (Cyclone) that originated over the ocean in a tropical low latitude bar but outside khetboriwen Equator because it has not yet appeared as tropical hurricanes occurred at the Equator. This storm occurred in the ocean or sea, with high temperatures ranging from 26 degrees Celsius and 27 degrees Celsius or more and have high vapor quantity. When it occurs, is often moved by wind mainly from the East to the West and then curves up towards the high latitude, and then merge the curve back to the East again. Tropical hurricanes occurred in several places in the world, and named differently according to the origin. Tropical hurricanes when they are in full growth that would be the most severe storm type one of those storms that occur in the world. Has a diameter of approximately 100 or more kilometres and occur with the wind blowing very strong? Air circulation system is to. By blowing merge in counterclockwise direction to the center of the storm in the northern hemisphere. Best in the southern hemisphere clockwise Robin blows. The more near the Center, the wind spin almost in a circle and has a highest speed. The maximum wind speed near the Center is used as a criterion to determine the severity of the storm. The yanomhatmuthon Pacific-North West-side configuration, and the South China Sea are divided according to the Treaty, as follows: -Tropical depression storm (tropical depression) the wind speed near the Center is up to 34 knot (63 km/h) -Storm hot zones (tropical storm) wind speed near the Center 34 knot (63 km/h) or more, but less than 64 knot (118 km/h) -Taifun (typhoon), the maximum wind speed near the Centre from 64 knot (118 km/hr) or more. For the Thai national affected by tropical hurricanes, "he said." the formation in the area of the Pacific Ocean and a tropical hurricane formation in the India ocean areas, which we called "cyclone" Although tropical hurricane formation in the ocean, India will not sign the country directly to Thai, but they can cause damage to Thai country as well. When the direction of movement into the area near the country's West side, Thai. In the case of hurricanes, tropical formation in the Pacific Ocean and the South China Sea, it will move into the Thai nation in the country's areas vary according to the season. The hurricane or tropical cyclone is a natural phenomenon that can damage it severely needs to have a wind speed greater than 64 knot (30 meters/second, miles/hour, or 74 118 km/hr) or more, and often have a "Hurricane eye" The center known as "the eye" is the wind and the air is transparent, there may be some slight rain clouds and surrounded by a large area radius of hundreds of kilometers. The eyes of this storm can be seen clearly from satellite photos as a small circle, there are no clouds around the eye is walled with approximate size 16-80 km, a severe storms and very whirlwind spin around. Ta Thus, in the area of tropical hurricanes move over. For the first time will appear transparent weather characteristics. When in front of a tropical Hurricane arrives, it appears the wind strength. Torrent and stormy winds and thunderstorms and tornado may appear to shout. While the eye storm arrives, the weather will be transparent again, and when the rear of the hurricane arrived, the weather will be worse than the first time again, and where the movement of clouds around the center of the storm formation is a prominent shell bottom band coil. Bands or rings that curve, competitive long distance filing out as much as the clouds were pulled into the spinning circle. The purpose of the study.1. to study the causes of occurrences of tropical revolving storm.2. to study the effect of tropical hurricanes occurred.3. to study ways to protectA preliminary agreement. 1. to know the problems of tropical hurricanes 2. to study ways to protectThe scope of the study. 1. in the period of 2 weeks. 2. by the survey. 3. population and sampleSpecific terms 1. mean storm wind 2. the encounter Means seen. 3. the problem means that must be considered.The benefits expected to be received 1. to study the impact of the hurricanes, tropical rucksack – however? 2. make the situation difficulties of the victims. 3. to recognize that what is tropical hurricanes. Assumption of research 1. to be aware of the causes of hurricanes. 2. to study the data protection guidelines for content reasons. 3. study to understand the impact that will occur.

1 chapter introduction, background and significance
is cyclone in Thailand may cause damage but has not happened in hurricanes.
provenances or problems within the tropical cyclone
.Tropical cyclone is the word around. To use for called hurricanes or cyclone (Cyclone) with native North Ocean in the tropical แถบละติจูด low. But outside of the equator.This storm formed in the ocean or sea, with high temperatures since 26 C or 27 degrees Celsius degree and quantity of steam is high. When it happens often moves with the wind from the east to the west, mostThe flow curve and return to the East. Tropical cyclones occur in several places in the world. And can be called vary according to source
.Tropical cyclone when condition, grow. Is one of the most violent storms in the world. With a diameter of about, since 100Circulation system of wind is possible. By blowing in the direction anticlockwise circulation towards the center of the storm in the northern hemisphere. The circulation in the southern hemisphere blowing clockwise. The nearer the wind to rotate nearly circular and has the highest speed
.Maximum wind speed near the center used as criteria for determining the severity of the storm. The Pacific Ocean in which district - Pacific North West. And the South China Sea is divided by international agreement as follows:
.- tropical depression (tropical depression) wind speed near the center, not 34 knots (63 km / h)
- พายุโซน hot. (tropical storm) wind speed near the center 34 knots (63 kilometers / hour) up to, but not 64 knots (118 kilometers / hour)
.- a typhoon (typhoon) maximum wind speed near the center since 64 knots (118 kilometers / hour) up

.The impact of "tropical cyclone formations in the area of the Pacific Ocean." Tropical cyclone formation and in the Indian Ocean, which we called "cyclone".But it can cause damage to the country as well. When the direction of movement into the area near the west side. In the case of a tropical cyclone formation in which the Pacific and the South China Sea.Different countries' seasonal
.Tropical cyclone, cyclone is a natural phenomenon that can damage was severe. There will be more than 64 knots wind speed (M / s, 3074 miles per hour, or 118 kilometers / hour) and above, and often have "eye of storm center or called" eye "is the area with wind calm. The weather by clouds and rain may be slightly.Eye of storm is obvious from satellite imagery, a small circle with no clouds. Around the eyes have walls around the width of about 16-80 kilometers. The area is very severe rainstorm and the wind swirling around the eyes!So, in the area of tropical cyclone moving through. The weather looks first appears transparent. When the front of the tropical cyclone to appear strong winds, heavy rain and thunder storm, wind force action soaked and may appear a tornado.Air is transparent. And when the back of the twister hit air worse again and violent than the first, which the movement of clouds around the center of the storm formation is a coiled spiral architecture.
