(10 marks) The seasonal variations in climate‚ in a tropical region‚ which includes temperature‚ precipitation and wind direction‚ are due to a number of factors. The tropical continental climate in Africa‚ north of the equator‚ can be described as transitional‚ as it is between the rainforest margins of the central African rainforest and also the desert margins of the Saharan desert. This results in a continual‚ gradual change to the climate‚ so that as the latitude increases

Jet Streams Jet streams are strong westerly winds that blow in a narrow band in Earth ’s upper atmosphere at the same altitudes at which airplanes fly. They form because of temperature variations between the poles and equator. There are two occurrences that results in the Jet Streams. The first occurrence would be when hot air rises from the tropics towards the North and South Poles subsequently the second occurrence is as the hot air is moving to the north and south poles from the tropics‚ the

The constellations that astronomers use to identify parts of the sky are not the same as the Zodiac signs used by astrologers. The Zodiac signs were identical to the constellations 2000 years ago when their modern names were first used. The Signs are an astrological convenience ignoring the differences between two different types of solar calendar. This is described further in The Calendar. The astrological signs are about a month out from the astronomical constellations. When an astrologer says

Earth Day is an annual event‚ celebrated on April 22‚ on which day events worldwide are held to demonstrate support for environmental protection. It was first celebrated in 1970‚ and is now coordinated globally by the Earth Day Network and celebrated in more than 192 countries each year. In 1969 at a UNESCO Conference in San Francisco‚ peace activist John McConnell proposed a day to honor the Earth and the concept of peace‚ to first be celebrated on March 21‚ 1970‚ the first day of spring in the

research. Firstly‚ Vietnam is located in the northern hemisphere. Secondly‚ with a long coastline of 3‚260 km with many important seaports in the SEA area‚ it is undoubtedly fits to Sachs and Gallup survey. However‚ because of the location near the Equator‚ Vietnam has tropical climate with temperature ranges from 5 to 37oC and annual rainfall is substantial in all regions and torrential in some‚ ranging from 1‚200 to 3‚000 millimeter per year. For this criteria‚ Vietnam does not meet the final pattern

referred to as the “dividing line” between the two atmospheres. It separates extremely warm air to the north and extremely cold air to the south in the case of the southern hemisphere. They have to stabilize out the massive heat that exists close to the equator and the cold air close to the poles. The warm air tries to move towards the south while the cold air tries to move towards the north. As a result mid latitude cyclones are formed to restore the balance in the regions affected by this scenario. A kink

Sunday‚ January 18‚ 2015 3:46 PM Many people wonder why we have the four seasons‚ Winter‚ Summer‚ Spring‚ and Fall. These seasons let us know things like what to wear‚ things to eat and places to go. Some people just think that’s the way the world is‚ But other people want to dig deeper. When people think of winter they think of snow‚ hot chocolate and other winter activities‚ Whereas Summer we think of the beach‚ and ice cold lemonade. Well let’s think about this- Why do we have seasons

Southern Hemisphere. These are average conditions and do not essentially reveal conditions on a particular day. As seasons change‚ the wind patterns shift north or south. So does the intertropical convergence zone‚ which moves back and forth across the Equator. Sailors called this zone the doldrums because its winds are normally weak. Latitude and angles of the suns rays As the Earth circles the sun‚ the tilt of its axis causes changes in the angle of which sun’s rays contact the earth and hence changes

Climate In tropical marine areas‚the ocean is largely responsible for creating the tropical marine climate system.In these areas there are two seasons‚ the wet season and the dry season. The average temperature ranges from 25-35 degrees celsius.The annual rainfall is between 1000-1500 mm . The trade winds in this area blow all year and are moist because they pass
