The high temperatures of the Asian landmass create an area of low pressure. Bangladesh is called the land of six seasons (Sadaritu). Characteristics of the rainy monsoon season.
Change ), CODE The diameter of a cyclone may range from 300 km to 600 km. The warm air being less dense rises above the cold air to produce the area of low pressure on the ground. In brief: characteristics of a tropical monsoon climate. Let’s find more characteristics of a tropical monsoon climate. Change ), You are commenting using your Google account. It has a tropical climate because of its physical location. Describe where the highest and lowest temperatures are found.
This results in heavy rainfall (see Figure 2.3). Average temperatures in July vary from about 27˚C in the southeast to 29˚C in the northwest of the country. From 1981 to 1985, 174 severe cyclones (with winds speeds of more than 24 km/hr) formed in the Bay of Bengal. Thunderstorms are tropical storms with thunder and lightning accompanied by heavy rain or hail. Usually individual thunderstorms in just one cell in a group of storms, which may be 30 km wide, lasting for more than five hours.
Describe the distribution of the rainfall (comment of the areas which receive the highest and lowest amounts). Most of the damage during a cyclone is done by the storm surges, which sometimes wash over entire offshore and large areas on the coast. Justify your answer. ( Log Out / However, the cold winter air that moves into the country from the northwestern part of India loses much of its intensity by the time it reaches the northwestern corner of the country. ( Log Out /
During such depressions, continuous heavy rainfall occurs in Bangladesh for 7 to 10 days. LOCATION The monsoon climate beyond the equatorial region between 10 and 25 and North… Average temperatures in April vary from about 27˚C in the northeast to 30˚C in the extreme west of the country.
They strike the coast nearly at eh same time that the center of the storm crosses the coast. Air from the surrounding area spirals inwards to replace the rising air. The geographical location (latitude, coastal or continental position) and physical settings (e.g. water) during the winter or low-sun season. Required fields are marked *. Rainfall which takes place during this time accounts for 10 to 25 percent of the annual total. The single most dominant element of the climate of Bangladesh is the rainfall. …to wet equatorial climates, tropical monsoon and trade-wind littoral climates exhibit a short dry season, usually in the low-sun (“winter”) season, and the highest temperatures generally occur at the end of this clear spell. After the withdrawal of the wet monsoon, which usually occurs in mid-October, rainfall diminishes at a rapid pace. Paper 2 Climate is the average state of the atmosphere near the earth’s surface over a long span of time. Average temperatures in January vary from about 17˚C in the northwestern and northeastern parts of 20˚-21˚C in the coastal areas. This spinning air can reach speeds of 200 km/hr and absorbs large amounts of moisture forming cumulonimbus clouds which result in heavy rain. At the same time, a low-pressure system develops over Australia and the Indian Ocean where it is warmer. As the winter season progresses into the pre-monsoon hot season, temperatures rise, reaching the maximum in April, which is the middle of the pre-monsoon hot season. The rainy season coincides with the summer monsoon.
It is bordered by the Himalayas to the north and by the Bay of Bengal to the south. ( Log Out / Among all the atmospheric disturbances, cyclones are the most destructive. Describe the rainfall distribution at each station. Rainfall in this season caused by weak tropical depressions that are brought from the Bay of Bengal into Bangladesh by the monsoon winds. At the same time, high pressure develops over the comparatively cooler the Indian Ocean. The average temperature in January varies from 17˚C in the northwest and northeast of the country to 20˚C-21˚C in the coastal areas.
April is usually the hottest month in the country. Surge-heights increase with the increase of wind speed. Astronomical tides in combination with cyclonic surges lead to higher water levels and hence severe flooding. The most destructive element of a cyclone is its accompanying surge. This is because of: Most of the damage caused by the cyclones occur in the coastal regions of Khulna, Patuakhali, Barisal, Noakhali and Chittagong and the offshore island of Bhola, Hatiya, Sandwip, Mapura, Kutubdia, Maheshkhali, Nijhum Dwip, Urir Char and other newly formed islands. This flow of wind is known as the summer monsoon circulation. Please log in using one of these methods to post your comment: You are commenting using your WordPress.com account.
As a result, warm moist air expands and rises rapidly. This rising air cools, condenses into water vapor forming cumulonimbus clouds. Geography 2230/2 Natural Topography: Location and Characteristics of Main Landforms, The hot and dry pre-monsoon season, from March to May, The rainy monsoon season, from June to October. The converse happens during the summer months. Look at a map in an atlas that shows the average annual rainfall for Bangladesh. ( Log Out / Widespread cloud cover lowers the temperature during the later of the pre-monsoon season. The Bay cyclones also move towards the eastern coast of India, towards Myanmar and occasionally into Sri Lanka. How far inland likely to be affected by a cyclone? Because of the country’s location in the tropical monsoon region, the amount of rainfall is very high. The cold air then sinks. The life cycle of a cyclone ends soon after the cyclone reaches land (landfall) because it is cut off from its moisture source.
