Verified Answer
With reference to the increased cyclonic activity in Arabian Sea and ...
Statement 1 is correct: The Arabian Sea is comparatively less prone to cyclonic storms than the Bay of Bengal due to colder sea surface temperature of Arabian Sea than Bay of Bengal, which is not favorable for the development and sustenance of cyclonic storms. Also, Bay of Bengal can receive remnants of cyclones originating in Pacific Ocean, which can intensify after reaching Bay of Bengal after crossing Kra isthmus of Thailand.
Statement 2 is correct: Indian Ocean Dipole is an irregular natural oscillation of Sea Surface Temperatures (SSTs) in which the western Indian Ocean becomes alternately warmer and then colder than the eastern part of the ocean. A positive IOD brings warmer-than-average SSTs to the Arabian Sea and cooler-than-average SSTs near Indonesia.
A warmer SST in Arabian Sea during positive IOD can promote strong cyclogenesis in Arabian Sea.

Increased Cyclonic Activity in Arabian Sea and Bay of Bengal in 2019
Introduction:
In 2019, both the Arabian Sea and the Bay of Bengal witnessed an increase in cyclonic activity. This led to severe weather events, including powerful cyclones and heavy rainfall, causing significant damage to lives and property in the coastal regions.
Statement 1: Arabian Sea is comparatively less prone to cyclonic storms than the Bay of Bengal.
This statement is incorrect. The Arabian Sea is not less prone to cyclonic storms compared to the Bay of Bengal. In fact, the Arabian Sea has witnessed several devastating cyclones in the past, including Cyclone Ockhi in 2017 and Cyclone Vayu in 2019. The region is susceptible to cyclonic activity, although it may not experience cyclones as frequently as the Bay of Bengal.
Statement 2: A positive Indian Ocean Dipole can cause strong cyclonic activity in the Arabian Sea.
This statement is correct. The Indian Ocean Dipole (IOD) is a climate phenomenon characterized by the difference in sea surface temperatures between the western and eastern parts of the Indian Ocean. When the western part of the Indian Ocean becomes significantly warmer than the eastern part, it is referred to as a positive IOD. This positive IOD can lead to strong cyclonic activity in the Arabian Sea.
Explanation:
1. Arabian Sea prone to cyclonic storms: The Arabian Sea is not less prone to cyclonic storms compared to the Bay of Bengal. While the Bay of Bengal is known for its higher frequency of cyclones, the Arabian Sea is also susceptible to cyclonic activity. The Arabian Sea has witnessed severe cyclones in the past, and its coastal regions are vulnerable to the impacts of these cyclones.
2. Positive Indian Ocean Dipole and cyclonic activity: The Indian Ocean Dipole (IOD) plays a significant role in influencing the weather patterns in the Indian Ocean region. A positive IOD occurs when the western part of the Indian Ocean becomes warmer than the eastern part. This temperature difference creates a gradient that influences the monsoon circulation and atmospheric conditions, leading to the intensification of cyclonic activity. A positive IOD can result in strong cyclonic storms in the Arabian Sea.
Conclusion:
In conclusion, the statement that the Arabian Sea is less prone to cyclonic storms than the Bay of Bengal is incorrect. Both regions are susceptible to cyclonic activity. Additionally, a positive Indian Ocean Dipole can cause the Arabian Sea to experience strong cyclonic activity. The increased cyclonic activity in both the Arabian Sea and the Bay of Bengal in 2019 highlights the need for effective disaster management and preparedness measures in the coastal regions of India.
