What is the root of the Bangladeshi nationality


Bangladesh is located on one of the largest deltas in the world, which is formed in particular by three main rivers and their multitude of tributaries. In a semicircle with a radius of about 400 km north of the Bay of Bengal (transliterated: Baṅgopasāgar) all rivers flow in a dense network or flow into the gulf. It is the delta of the river system that is dominated by the rivers Ganges / Padma (transliterated: Gaṅgā, Padmā), Brahmaputra / Yamuna (transliterated: Brahmaputra, Yamunā), Meghna (transliterated: MeghꞋnā). These rivers are international rivers and have different names in the areas through which they flow. Ganges and Brahmaputra are the names used in India (transliterated: Bhārat) and probably more common internationally. They are called Padma and Yamuna in Bangladesh, but this does not rule out the fact that the name used in India is not known or used there.

The Bangladeshi part of the Joint River Commission in Bangladesh has over 400 rivers in total. These include 54 rivers that flow mostly from India to Bangladesh and three rivers that come from Myanmar. The rivers Ganges / Padma and Brahmaputra / Yamuna are counted among the ten largest rivers on earth, measured by the average water volume at the lower reaches of the respective river. Ganges / Padma is mostly classified as the fourth largest, Brahmaputra / Yamuna as the ninth largest river.

The climate in which Bangladesh is located also contributes to the size of these rivers. Bangladesh is in the northern tropic, which means tropical climate and monsoons (transliterated:mausumi) means. Usually from March to late May, in Bangladesh as summer or 'heat' (transliterated:grīṣmagrīṣmakāl), the average temperature is 26-29 ° C. Evaporation is greatest during the summer. At times there are thunderstorms and cyclones (transliterated:ghūrṇijhaṙjhaṙ) due to these climatic conditions. Cyclones are tropical cyclones that can develop high wind speeds. For example, the maximum speed of cyclone Sidr (transliterated: SiḍꞋr) was 215 km / h in 2007. They mostly affect the coastal areas of Bangladesh and neighboring countries. June to September is the rainy season (transliterated:barṣā). Precipitation, humidity and degree of cloudiness are highest during this period. Up to 80% of the annual precipitation falls during the four months at constant temperatures, an average of 30 ° C. The amount of annual precipitation varies in the individual Bangladeshi areas. In the northeast of the Sylhet district (transliterated: Sileṭ), on the border with the Indian state of Meghalaya (transliterated (bengal.): Meghālaẏ), the country's highest annual rainfall is measured at around 5,500 mm per year. In the capital Dhaka (transliterated: Ḍhākā) it is about 1,750 mm. After the rainy season, a kind of autumn follows from the end of September to mid-November. Then the temperatures are around 27 ° C and the weather conditions are hot, sunny and humid. At this time of year, too, cyclones can form over the Bay of Bengal and damage the coastal regions of the Gulf. The dry season after that, from December to February, is called winter or cold season (transliterated:śītꞋkālśīt) designated. The temperatures are then around 15 ° C.

The average annual temperature in Bangladesh is given as 25 ° C. However, under special conditions and in certain areas, maximum temperatures of over 40 ° C or lowest temperatures of 4 ° C can occur. The latter and also ground frost can form during the dry season - very rarely and exclusively on exposed relief elevations, for example in the Barind Tract (transliterated: Barendra Bhūmi) in western Bangladesh.

Winds are usually light. They blow depending on the season - before and during the rainy season, air flows in a north-westerly, northerly direction, which is reversed after the rainy season. A few exceptions are thunderstorms and cyclones before and after the rainy season. Because cyclones occur more frequently in these periods, the casual term 'cyclone season' can sometimes be found for these months - in conversation with locals or now in local and international media.

Bangladesh's land area is 147,570 km². Of this, around 9,700 km² are permanently flooded by rivers, lakes, artificially created reservoirs, baths and the like, i.e. also during the less rainy period between October and April. However, these figures vary widely. The two countries India and Myanmar are the only direct neighbors of Bangladesh. The border with India is approximately 4,142 km and that with Myanmar 271 km.

Bangladesh consists of different types of relief. The so-called Chittagong Hill Tracts (transliterated: Pārbatya Caṭṭagrām) are the only mountainous region. They are located in the southeast of Bangladesh. The highest mountain there is 1,052 m high and at the same time the highest point in the entire country. With a few exceptions, the relief in the rest of Bangladesh does not exceed 10 m above sea level. This type of landscape takes up around 80% of the country's area and is characterized by wide plains as well as lowlands and beds of water. The majority of Bangladesh is thus a wide alluvial plain, in which a lot of water cyclically collects through rivers and rainwater and runs wide. Seasonal, meter-high flooding that lasts for months in some areas (transliterated:banyā) occur naturally in this delta and have also been archaeologically proven for centuries, for example. An exception to this type of landscape is the Chittagong Hill Tracts, the Barind Trakt (transliterated: Barendra Bhūmi). It is an elevation and platform of about 20-40 m above sea level, which lies in western Bangladesh on the border with India and continues in the neighboring Indian state of West Bengal (transliterated: PaścimꞋbaṅga).
