Bangladesh is one of the most vulnerable countries in the world with around 718000 deaths in the past fifty years. This country is especially in danger for cyclones because of its locations at the triangular-shaped Bay of Bengal. The scientific scenario suggests that enlarged sea surface temperature will intensify cyclone movement. Tropical cyclone generates storm surge. Storm surges severely change the coastal environment, damage coastal structures, destroy forests, crops, inundate the coastline with saltwater and loss of lives. Due to overcrowding in the mainland in Bangladesh, poor and landless people live in the coast and they face frequent cyclones and associated surges. They affect to have food and drinking water; in danger the transmission risks of infectious diseases, such as diarrhoea, malaria, eye infections, skin diseases, etc. Some problems following a cyclone usually create for their low literacy rate and poor knowledge of the environment. The tangible monitoring and warning of the cyclones and associated surges should be given more priority for the region. The main objectives of this paper are to highlight the existing activities as the model in storm surges and related areas in the Bay of Bengal. We would explain the progress of a location-specific real-time standpoint prediction system for providing effective and timely surge forecasts. We would also introduce a model through numerical experiments with severe cyclone April 1991 to predict the storm surges that would be used to reduce economic losses and the number of death tolls during a strong storm surge in the coastal area of Bangladesh.

“…The Shallowness of water, thickly populated low lying islands of different shapes, high tidal range, fresh water and sediment discharge through the world's second largest river system Ganges-Brahmaputra-Meghna etc. make this region the world's most vulnerable one, but the area is insufficiently studied [6]. Thus the coastal region of Bangladesh is chosen as our study area.…”

“…But, the model was a stair-step model and the study was conducted using the uniform distribution of grid lines in the radial direction without ensuring fine mesh resolution. But the accuracy of the result obtained from a stair-step model highly depends among other on grid resolution [6]. Also, for accurate prediction of surge associated with a storm, the bottom topographic details of the region, especially for the Meghna estuarine area should properly be incorporated, which necessitates very high resolution of grids [3].…”

In this study, a complex geometric domain having a colour picture is approximated through a stair- step representation of the coastal and island boundaries to make it suitable for implementing finite difference method in solving shallow water equations (SWEs) in polar coordinates. As a complex domain, we choose the coastal region of Bangladesh situated at the northern tip of the Bay of Bengal (BOB). To cover the whole coastal region, the pole is selected at the point in the plane assuming it on the mean sea level (MSL). Along the tangential direction, 265 uniformly distributive straight lines are considered through the pole and 959 circular grid lines centered at are drawn towards the radial direction covering up to latitude in the BOB. Firstly, a matrix with 960´265 computational grids is constructed from the colour information of the picture. By representing the grids with suitable notations, a proper stair-step algorithm is employed to the matrix obtained with the 960´265 grids to approximate the coastal and island boundaries to the nearest finite difference grid lines using an Arakawa C-grid system. The whole procedure is done with our developed MATLAB program. The grids representing the coastal stations are also identified closely in the obtained approximated domain. Such a type of presentation of the coastal geometry of the region of interest is found to incorporate its complexities properly with minimum computational grid points. GANIT J. Bangladesh Math.

In May 2020, a category-5 tropical cyclone (TC) Amphan formed in the Bay of Bengal and struck the coasts of India and Bangladesh. In this study, the relevant dynamic characteristics and aftermaths of Amphan are documented. Through detailed investigation of the reanalysis and observation data, spatiotemporal varying characteristics of the atmospheric and oceanic parameters during the Amphan propagation process were analyzed. Due to a wide range of high sea surface temperature anomaly, Amphan developed rapidly and ultimately led to the local heavy precipitation and strong winds in the coastal areas during its passage. It is also noted that the recorded wave height, wave period, and current speed all amplified when Amphan passed by and the characteristics of wave and current directions are also consistent with the temporal variation of the corresponding wind field. Meanwhile, Amphan occurred in accompany with the ongoing COVID-19 pandemic. In Khulna Division of Bangladesh, the number of newly confirmed COVID-19 cases increased rapidly after Amphan landing, which however was almost nil before the event, indicating there might exist a possible correlation between Amphan and the intensive outbreak of the local COVID-19, and particular attentions should be paid to deal with the multi-type, coexisting disasters if different or even conflicting measures are required.
