Rivers and Lakes
Bangladesh is a land of rivers that crisscrossed all the way through the mostly plane territories of the country. They consist of hundreds of brooks and a superior quantity of big ones. The Ganges (Ganga) is known as the Padma lower the summit where it is coupled by the Jamuna River, the name prearranged to the lowermost segment of the main waterway of the Brahmaputra. The collective tributary is then called the Meghna underneath its convergence with a much smaller offshoot of the same name. In the dry season the abundant deltaic distributaries that bootlace the topography may be more than a few kilometers extensive as they in the neighborhood of the Bay of Bengal, but at the elevation of the summer monsoon season they band together into an exceptionally broad vastness of silt-laden water. In much of the delta, for that reason, homes must be constructed on mud platforms or embankments high an adequate amount of to stay behind on top of the level of all but the maximum floods. In non-monsoon months the open to the elements land is pocked with water-filled have access to all-time low, or tanks, from which the sludge for the embankments was excavated. all the way through the country there are bils, haors and lakes that gather the need of consumption, bathing and irrigating water.
Seasons
Traditionally Bangladeshis subdivide the year into six seasons: Grismo (summer), Barsha (rainy), Sharat (autumn), Hemanto (cool), Sheet (winter), and Bashonto (spring). For practical purposes, however, three seasons are distinguishable: summer , rainy, and winter
Climate
Bangladesh has a tropical monsoon-type climate, with a hot and rainy summer and a dry winter. January is the coolest month with temperatures averaging near 26 deg C (78 d F) and April the warmest with temperatures from 33 to 36 deg C (91 to 96 deg F). The climate is one of the wettest in the world. Most places receive more than 1,525 mm of rain a year, and areas near the hills receive 5,080 mm ). Most rains occur during the monsoon (June-September) and little in winter (November-February).
Bangladesh is subject to devastating cyclones, originating over the Bay of Bengal, in the periods of April to May and September to November. Often accompanied by surging waves, these storms can cause great damage and loss of life. The cyclone of November 1970, in which about 500,000 lives were lost in Bangladesh, was one of the worst natural disasters of the country in the 20th century.
In Dhaka the average temperature in January is about 19° C (about 66° F), and in May about 29° C (about 84° F).
Flora and Fauna
Chittagong Hill Tracts, portions of the Madhupur Tract, and the Sundarbans (a great tidal mangrove forest in the southwestern corner of the country) are principal vegetation in Bangladesh. The wooded area amount to less than one-sixth of the total area. Broadleaf evergreen species characterize the hilly regions, and deciduous trees, such as acacia and banyan, are common in the drier plains areas. Commercially valuable trees in Bangladesh include sundari (hence the name Sundarbans), gewa, sal (mainly growing in the Madhupur Tract), and garan (in the Chittagong Hill Tracts). Village groves inslude fruit trees (mango and jackfruit, for instance) and date and areca (betel) palms. The country also has many varieties of bamboo.
Bangladesh is rich in fauna, including nearly 250 indigenous species of mammals, 750 types of birds, 150 kinds of reptiles and amphibians, and 200 varieties of marine and freshwater fish. The rhesus monkey is common, and gibbons and lemurs are also found.
The Sundarbans area is one of the principal remaining domains of the Royal Bengal tiger, and herds of elephants and many leopards inhabit the Chittagong Hill Tracts. Other animals living in Bangladesh include mongoose, jackal, Bengal fox, wild boar, parakeet, kingfisher, vulture, and swamp crocodile.
Mineral Resources
Bangladesh is not so rich in mineral resources. The principal energy resource, natural gas, is found in several small fields in the northeastern part. With the assistance of some foreign especially American companies gas expedition has increased. There is a coalfield in the northwest and large peat beds underlie most of the delta. Limestone and pottery clays are found in the northeastern Bangladesh.
