The urban heat island effect is a phenomenon in which urban areas experience higher temperatures than rural areas due to the concentration of heat-absorbing surfaces and human activities.
Precipitation Patterns and Rainfall Distribution
February is a transitional month in Sri Lanka, characterized by the retreat of the northeast monsoon and the onset of the inter-monsoonal period. During this time, the country experiences varying levels of precipitation, with the Intertropical Convergence Zone (ITCZ) playing a significant role in shaping the precipitation patterns.
Relationship with the Intertropical Convergence Zone (ITCZ), February sri lanka weather
The ITCZ is a belt of low-pressure systems that encircles the equator, marking the boundary between the trade winds and the westerly winds. In February, the ITCZ is at its northernmost position, extending over Sri Lanka and bringing with it warm, moist air from the Indian Ocean. As a result, the country experiences an increase in precipitation, particularly in the northern and eastern parts.
The ITCZ’s movement also influences the formation and movement of tropical cyclones in the Indian Ocean, which can impact Sri Lanka’s precipitation patterns. These cyclones can bring heavy rainfall and strong winds, leading to flash flooding and landslides in some parts of the country.
A tropical cyclone that affects Sri Lanka in February can bring up to 200 mm of rainfall over a 24-hour period.
Geography-Driven Rainfall Distribution
Sri Lanka’s geography plays a crucial role in determining the distribution of rainfall across its regions. The country’s mountainous terrain creates a rain shadow effect, with the western and southern parts receiving higher rainfall compared to the eastern and northern regions.
The western coastal plains, particularly around Colombo and Galle, receive significant rainfall due to the prevailing southwest monsoon winds. In contrast, the eastern coast of the country experiences a drier climate during the inter-monsoonal period.
Observations from Meteorological Stations
Meteorological stations across Sri Lanka have recorded varying levels of precipitation during February. The northern city of Jaffna has recorded some of the highest rainfall totals, with an average of 150 mm over the month. In contrast, the eastern coastal town of Trincomalee has recorded relatively low rainfall, with an average of 30 mm.
