To mitigate these challenges, efforts are being made to improve weather forecasting and early warning systems, implement flood control measures, and promote sustainable water conservation practices.

Unexpected Snowfall

Bangladesh, a tropical country known for its warm and humid climate, experienced an unprecedented snowfall in Cox’s Bazar, a coastal district bordering Myanmar.

Year-Round High Relative Humidity

Throughout the year, Cox’s Bazar maintains a high relative humidity. Even during the drier months (November to March), humidity levels average around 60-70%. The coastal location and proximity to the Indian Ocean contribute to the consistently high moisture content in the air, resulting in a generally humid climate.

Wind speeds during the monsoon season can reach up to 50 knots or higher, making it less favorable for outdoor activities.

Influence on Weather and Climate

The varying wind patterns in Cox’s Bazar significantly impact the region’s weather and climate. The dry and cool trade winds during winter create pleasant conditions, while the warm and humid monsoon winds bring abundant rainfall. This seasonal precipitation supports the lush vegetation and vibrant marine life for which Cox’s Bazar is renowned. Furthermore, the strong monsoon winds help regulate the temperature and humidity levels, preventing the region from experiencing extreme heat or cold. The wind patterns also play a crucial role in the formation and dissipation of cyclones, which can affect the coastal areas of Bangladesh and cause significant damage.

Solar Energy Potential

Cox’s Bazar, renowned for its picturesque beaches, holds immense potential for solar energy development. The region receives abundant sunlight throughout the year, averaging over 5.5 kWh/m²/day. This favorable climate makes solar energy a viable option for meeting the growing energy demands of the area. With a significant portion of the population lacking access to reliable electricity, solar energy presents a promising solution for providing affordable, sustainable power.

Current Initiatives and Future Prospects

Several initiatives are underway to harness the solar energy potential of Cox’s Bazar. The Chittagong Hill Tracts Development Board (CHTDB) is implementing a large-scale solar project involving the installation of 30 MW of solar panels. Additionally, numerous smaller-scale solar installations have been established in villages and remote communities, providing off-grid power to households and businesses. The government has set ambitious targets for increasing solar energy production, with a goal of generating 40% of its electricity from renewable sources by 2041. These initiatives are expected to further strengthen the role of solar energy in Cox’s Bazar and contribute to the region’s sustainable energy future.

Coastal Geomorphology

Cox’s Bazar’s topography is predominantly characterized by its coastal geomorphology. The coastal zone consists of a narrow sandy beach (~150-200 m wide) backed by dunes (~5-15 m high). These dunes are composed of fine to medium-grained sand and have a gentle slope towards the sea. The beach slopes gently into the Bay of Bengal, with a gradient of approximately 1:20. The tidal range is relatively high (3-4 m), resulting in the formation of a wide intertidal zone.

Subaerial Landforms

Beyond the coastal zone, the topography of Cox’s Bazar transitions into subaerial landforms. The terrain is generally flat to slightly undulating, with numerous small rivers and channels crisscrossing the area. The underlying geology is composed of unconsolidated alluvial sediments (silt, clay, and sand) deposited by the Ganges-Brahmaputra delta. The alluvial plains are interspersed with isolated hills of sandstone and shale, which represent remnants of an older geological formation. The highest point in Cox’s Bazar is Mount Harishchandra (345 m), located in the northern part of the district.
