Types of Clouds

Narayanganj, situated in central Bangladesh, experiences diverse cloud formations due to its tropical monsoon climate. During the dry season (November-April), high-altitude cirrus clouds often grace the sky, characterized by their feathery and wispy appearance. These clouds are composed of ice crystals and indicate fair weather conditions. As the monsoon season approaches (May-October), towering cumulonimbus clouds become more prevalent. These clouds can reach immense heights and produce heavy rainfall, thunderstorms, and occasionally hail. Cumulus clouds, with their puff-like form, are common throughout the year and are associated with fair weather or light precipitation.

Cloud Dynamics

Cloud formation in Narayanganj is influenced by various atmospheric factors, including temperature, humidity, and air pressure. Air masses rising due to convection or orographic lifting cool and condense, forming clouds. The vast Ganges-Brahmaputra delta, in which Narayanganj lies, provides a low-lying area that facilitates the accumulation of moisture and formation of clouds. The seasonal rainfall patterns and intense heat during the summer months contribute to the frequent occurrence of heavy cloud cover in Narayanganj. The city’s proximity to the Bay of Bengal also plays a role, as moisture-laden winds from the coast further enhance cloud formation.

Annual Rainfall and Distribution

During these months, the city can experience intense thunderstorms and occasional flooding. In contrast, the dry season (November to April) is relatively drier, with occasional light showers and periods of drought.

Influence of Monsoon and Geographic Factors

Narayanganj’s precipitation patterns are heavily influenced by the seasonal monsoon winds. During the southwest monsoon, moist air from the Bay of Bengal is drawn towards the Indian subcontinent, bringing heavy rainfall to the region. The city’s location within the Ganges-Brahmaputra-Meghna river delta also contributes to its high rainfall. The confluence of major rivers and the presence of numerous wetlands create a favorable environment for moisture retention and precipitation formation. Additionally, Narayanganj’s proximity to the Bay of Bengal further increases the city’s susceptibility to tropical cyclones and storms, which can bring additional rainfall.

Seasonal Rainfall Patterns

Narayanganj, a city in Bangladesh, experiences significant rainfall during the monsoon season from June to October. During this period, the city receives an average of over 1,200 millimeters of rain, with heavy downpours being common.
