Introduction

South Asia, a region prone to tropical cyclones, has experienced several significant storms in the past two years. These cyclones have caused widespread impact, affecting millions of lives and causing substantial damage to infrastructure and agriculture. In this article, we will review the notable cyclones that have hit the region in the years 2020 to 2023, and discuss the implications of these storms on the region.

Notable Cyclones in South Asia, 2020-2023

As of August 2023, several significant cyclones have affected South Asia. Notable among them are:

Cyclone Amphan (May 2020): One of the strongest cyclones to hit the region, affecting India and Bangladesh. Cyclone Yaas (May 2021): Impacted India’s eastern coast, particularly Odisha and West Bengal. Cyclone Tauktae (May 2021): A powerful cyclone that affected the western coast of India, particularly Gujarat. Cyclone Jawad (December 2021): Affected parts of India and Sri Lanka.

In total, there have been at least six notable cyclones affecting South Asia from mid-2021 to mid-2023. The exact number may vary depending on how one counts less severe storms or disturbances. For the most accurate and updated information, it is best to consult meteorological data from authoritative sources.

Cyclone Frequency in South Asia

While the North Indian Ocean Basin, which covers the entire South Asia coast, does not spawn many tropical cyclones, the frequency of these storms when they do occur can be significant. The North Indian Ocean cyclone season has seen various patterns in recent years. For instance:

2015: 12 depressions out of which 4 went on to become cyclonic storms. 2016: 9 depressions out of which 4 went on to become cyclonic storms.

These statistics underscore the variability in cyclone activity, with significant events spaced out over several years. Additionally, the Indian Meteorological Department (IMD) provides an official list of cyclones, which can be accessed at their official site.

Impact of Cyclones on South Asia

The impact of these cyclones has been substantial. For example, Cyclone Amphan in May 2020 affected millions of people in India and Bangladesh, causing extensive damage to infrastructure, crops, and homes. Similarly, Cyclone Yaas in May 2021 wreaked havoc on the eastern coast of India, particularly in Odisha and West Bengal, leading to deaths and extensive loss of property.

Conclusion

The frequency and impact of cyclones in South Asia highlight the need for better preparedness and disaster management strategies. As we move forward, it is crucial to pay attention to these tropical cyclones, given their potential for devastating impacts. By understanding the patterns and preparing accordingly, the region can better protect its people and infrastructure against the adverse effects of these powerful storms.
