Mangaluru, Aug 19: In recent days, a noticeable shift in weather patterns has occurred in the coastal region of Karnataka. After a period of sunshine following the monsoon's fury, sudden showers resembling post-monsoon rains have begun.

Typically, monsoon rains are brought by clouds arriving from the west. However, in the past few days, clouds have been moving in from the east. A significant change has been observed within a 30 to 40 km radius, a phenomenon known as the localized effect. This effect creates stark contrasts in moisture levels in the air between different areas. According to IMD officials, temperature variations have been noted across various parts of the city.

In some places, local clouds turn dark rapidly, leading to sudden downpours, often accompanied by thunder and lightning, especially in the afternoons or evenings. For example, Panja, Kollamogru, and Subramanya have experienced heavy rains in the evenings and nights over the past few days. This sudden burst of rain is attributed to changing weather patterns. The rainy clouds arrive from the southwest and move towards the Bay of Bengal via Sri Lanka, using the Karnataka coast. From there, they turn and re-enter Karnataka from Tamil Nadu.

As these clouds form over the Bay of Bengal, they merge with local clouds, resulting in heavy rainfall. Many parts of Kerala and Karnataka have become increasingly moist, leading to decreased temperatures and increased atmospheric pressure. Clouds arriving from the Arabian Sea tend to avoid high-pressure areas, moving instead towards low-pressure regions.

Typically, monsoon intensity is consistent throughout the coastal districts. However, recent patterns have shown significant variation: while it rains heavily in Sullia, there may be sunshine in Udupi and Mangaluru. For instance, the amount of rain that fell in Sullia between August 14 and 17 was much higher than in Mangaluru or Udupi.
