Factors Influencing Heavy Rainfall in Sri Lanka During December
Heavy rainfall events in Sri Lanka during December can have significant impacts on the country, including flash flooding, landslides, and damage to property and infrastructure. Understanding the factors that contribute to these events can help mitigate their effects and inform early warning systems.
One of the primary factors influencing heavy rainfall in Sri Lanka during December is the position and intensity of the Intertropical Convergence Zone (ITCZ). The ITCZ is a belt of low-pressure systems near the equator, where the trade winds from the northern and southern hemispheres converge. During December, the ITCZ is located near the tropics, drawing in warm, moist air from the Bay of Bengal and the Indian Ocean. When this moist air converges with the cooler air from the surrounding high-pressure systems, it can lead to heavy rainfall events.
El Nino and La Nina Events
The El Nino-Southern Oscillation (ENSO) is a natural climate pattern that affects the Pacific Ocean and has significant impacts on global weather patterns. During El Nino events, the trade winds that normally blow from east to west along the equator weaken or even reverse direction, allowing warm water from the western Pacific to flow towards the eastern Pacific. This can lead to an increase in rainfall in certain regions, including Sri Lanka, due to the warmer sea surface temperatures and the resulting increased atmospheric moisture.
During La Nina events, the opposite occurs, with the trade winds strengthening and pushing the warm water towards the western Pacific. This can lead to a decrease in rainfall in regions such as Sri Lanka, due to the cooler sea surface temperatures and reduced atmospheric moisture.
Topography and Rainfall Intensity
Sri Lanka’s unique topography plays a significant role in shaping rainfall intensity and distribution across different regions. The island’s mountainous regions, including the Central Highlands and the Knuckles Mountain Range, are capable of trapping and forcing warm, moist air to rise, resulting in increased rainfall. This orographic effect can lead to heavy rainfall events in regions such as the Ratnapura district, which is located in the southwestern part of the island.
In contrast, regions such as the Hambantota district, which is located in the eastern part of the island, tend to experience drier conditions due to the influence of the prevailing southwesterly winds. These winds bring dry air from the Indian Ocean, which can suppress rainfall in these regions.
Table: Average Rainfall and Temperature in Major Cities of Sri Lanka During December
| City | Average Rainfall (mm) | Average Temperature (°C) |
|---|---|---|
| Colombo | 145 | 28.5 |
| Kandy | 190 | 22.5 |
| Galle | 80 | 28.2 |
| Jaffna | 50 | 31.5 |
These factors interact with one another and with other regional and global climate patterns to produce the complex weather patterns observed in Sri Lanka during December. Understanding these factors can help mitigate the impacts of heavy rainfall events and ensure the safety and well-being of the country’s citizens.
