Thiruvananthapuram – Cyclone formed over southern Tamil Nadu has submerged many parts of the capital. As westerly winds strengthened, more clouds reached the Kerala coast and the rain intensified. Although the Met Office had issued a yellow alert, the rainfall equivalent to a red alert was received on Saturday night. Even though it was expected to rain, the weather watchers did not expect such a heavy rain.
A cyclone formed over the southeast Arabian Sea on Saturday. Later it moved to southern Tamil Nadu. Cyclonic circulation is called Chakrawatchuzhi in Malayalam. Cyclone formation is the first stage of cyclone formation. The weak circulation of wind before the formation of low pressure is called cyclonic circulation.
Fire rescue personnel rescue people, including those working at the Technopark, from the hostel at Kazhakoottam Mullivila.
Due to the pressure difference in the atmosphere, the wind becomes a vortex. The weak winds may strengthen later and become a low pressure. Not all cyclones are low pressure. Depression can intensify into severe depression and extreme depression. Cyclones form when they re-intensify. Not every cyclone will bring rain to Kerala. Factors such as wind strength and vortex location are important.
Due to the high water level in Edava-Nadayara dam following heavy rains, the water from the dam is flowing into the sea through a breach in Paravur Tekum part of Kollam district border. There are also those who ignore the flow in the estuary and come to have fun in the water. Image: Arvind Venugopal ∙ Manorama
Due to the strong westerly winds due to cyclonic circulation, some parts of Thiruvananthapuram and Kollam districts received heavy rainfall. Rain clouds were already present in these areas. As the west wind became stronger, the rain clouds increased. It rained continuously from Saturday evening till Sunday morning. In the previous 24 hours till 8 am on Sunday, Vellayani in Thiruvananthapuram district received 216 mm of rain. Thiruvananthapuram 211.4 mm, Ponmudi 211 mm, Neyyar Dam 200.2 mm, Neyyatinkara 188 mm. Thiruvananthapuram received 333.9 mm of rain in the first 15 days of October. 129.2 mm should normally be obtained.
Rescue: People are being evacuated from flooded houses in Mulluvila near Kazhakootam Technopark.
The strong El Nino phenomenon in the Pacific Ocean and the Indian Ocean Dipole phenomenon created favorable conditions for rainfall. The difference in surface temperature between the western Indian Ocean and the eastern Indian Ocean is called the Indian Ocean Dipole. -.4 to +.4 is the neutral condition. If it is above this, it is said to be positive. One of the reasons for rainfall from September is that the Indian Ocean Dipole is positive.
The temperature difference between the two oceans has been up to 1.85 degrees. Officials of the Kerala Disaster Management Authority said that this is only a factor of getting rain and it is not always rain due to this phenomenon. It doesn’t matter if the rain clouds form. Westerly winds should also be received. Westerly wind got strong yesterday.

K. Santhosh, director of Meteorological Center said that cyclonic circulation is the main reason for heavy rain on Saturday. Cyclone which was in South Tamilnadu area suddenly moved and came towards Kerala. K. Santosh said that the strong winds from the Arabian Sea and the Indian Ocean were also a factor in the heavy rains. According to weather experts, there is a possibility of low pressure forming in the Arabian Sea in the next 48 hours. A cyclone has formed in the Bay of Bengal. Heavy rain is likely in hilly areas of Palakkad, Malappuram and Wayanad districts.
