Bangladesh has a subtropical monsoon climate characterized by
wide seasonal variations in rainfall, moderately warm temperatures,
and high humidity. Regional climatic differences in this flat
country are minor. Three seasons are generally recognized: a hot,
humid summer from March to June; a cool, rainy monsoon season from
June to October; and a cool, dry winter from October to March. In
general, maximum summer temperatures range between 32°C and
38°C.
April is the warmest month in most parts of the country. January is
the coldest month, when the average temperature for most of the
country is 10°C.
Winds are mostly from the north and northwest in the winter,
blowing gently at one to three kilometers per hour in northern and
central areas and three to six kilometers per hour near the coast.
From March to May, violent thunderstorms, called northwesters by
local English speakers, produce winds of up to sixty kilometers per
hour. During the intense storms of the early summer and late
monsoon season, southerly winds of more than 160 kilometers per
hour cause waves to crest as high as 6 meters in the Bay of Bengal,
which brings disastrous flooding to coastal areas.
Heavy rainfall is characteristic of Bangladesh. With the
exception of the relatively dry western region of Rajshahi, where
the annual rainfall is about 160 centimeters, most parts of the
country receive at least 200 centimeters of rainfall per year
(see
fig. 1). Because of its location just south of the foothills of the
Himalayas, where monsoon winds turn west and northwest, the region
of Sylhet in northeastern Bangladesh receives the greatest average
precipitation. From 1977 to 1986, annual rainfall in that region
ranged between 328 and 478 centimeters per year. Average daily
humidity ranged from March lows of between 45 and 71 percent to
July highs of between 84 and 92 percent, based on readings taken at
selected stations nationwide in 1986
(see
fig. 3;
table 2,
Appendix).
About 80 percent of Bangladesh's rain falls during the monsoon
season. The monsoons result from the contrasts between low and high
air pressure areas that result from differential heating of land
and water. During the hot months of April and May hot air rises
over the Indian subcontinent, creating low-pressure areas into
which rush cooler, moisture-bearing winds from the Indian Ocean.
This is the southwest monsoon, commencing in June and usually
lasting through September. Dividing against the Indian landmass,
the monsoon flows in two branches, one of which strikes western
India. The other travels up the Bay of Bengal and over eastern
India and Bangladesh, crossing the plain to the north and northeast
before being turned to the west and northwest by the foothills of
the Himalayas
(see
fig. 4).
Natural calamities, such as floods, tropical cyclones,
tornadoes, and tidal bores--destructive waves or floods caused by
flood tides rushing up estuaries--ravage the country, particularly
the coastal belt, almost every year. Between 1947 and 1988,
thirteen severe cyclones hit Bangladesh, causing enormous loss of
life and property. In May 1985, for example, a severe cyclonic
storm packing 154 kilometer-per-hour winds and waves 4 meters high
swept into southeastern and southern Bangladesh, killing more than
11,000 persons, damaging more than 94,000 houses, killing some
135,000 head of livestock, and damaging nearly 400 kilometers of
critically needed embankments. Annual monsoon flooding results in
the loss of human life, damage to property and communication
systems, and a shortage of drinking water, which leads to the
spread of disease. For example, in 1988 two-thirds of Bangladesh's
sixty-four districts experienced extensive flood damage in the wake
of unusually heavy rains that flooded the river systems. Millions
were left homeless and without potable water. Half of Dhaka,
including the runways at the Zia International Airport--an
important transit point for disaster relief supplies--was flooded.
About 2 million tons of crops were reported destroyed, and relief
work was rendered even more challenging than usual because the
flood made transportation of any kind exceedingly difficult.
There are no precautions against cyclones and tidal bores
except giving advance warning and providing safe public buildings
where people may take shelter. Adequate infrastructure and air
transport facilities that would ease the sufferings of the affected
people had not been established by the late 1980s. Efforts by the
government under the Third Five-Year Plan (1985-90) were directed
toward accurate and timely forecast capability through
agrometeorology, marine meteorology, oceanography,
hydrometeorology, and seismology. Necessary expert services,
equipment, and training facilities were expected to be developed
under the United Nations Development Programme
(see Foreign Assistance
, ch. 3).
Background | | Europeans began to set up trading posts in the area of Bangladesh in the 16th century; eventually the British came to dominate the region and it became part of British India. In 1947, West Pakistan and East Bengal (both primarily Muslim) separated from India (largely Hindu) and jointly became the new country of Pakistan. East Bengal became East Pakistan in 1955, but the awkward arrangement of a two-part country with its territorial units separated by 1,600 km left the Bengalis marginalized and dissatisfied. East Pakistan seceded from its union with West Pakistan in 1971 and was renamed Bangladesh. A military-backed, emergency caretaker regime suspended parliamentary elections planned for January 2007 in an effort to reform the political system and root out corruption. In contrast to the strikes and violent street rallies that had marked Bangladeshi politics in previous years, the parliamentary elections finally held in late December 2008 were mostly peaceful and Sheikh HASINA Wajed was reelected prime minister. About a third of this extremely poor country floods annually during the monsoon rainy season, hampering economic development.

|
Economy - overview | | The economy has grown 5-6% per year since 1996 despite inefficient state-owned enterprises, delays in exploiting natural gas resources, insufficient power supplies, and slow implementation of economic reforms. Bangladesh remains a poor, overpopulated, and inefficiently-governed nation. Although more than half of GDP is generated through the service sector, nearly two-thirds of Bangladeshis are employed in the agriculture sector, with rice as the single-most-important product. Garment exports and remittances from Bangladeshis working overseas, mainly in the Middle East and East Asia, fuel economic growth. In 2008 Bangladesh pursued a monetary policy aimed at maintaining high employment, but created higher inflation in the process.
