What are bomb cyclones? When cold air clashes with warm air, like air over warm ocean waters, bomb cyclones form. A process known as bombogenesis, also known as a bomb cyclone, is responsible for the production of this rapidly intensifying large cooling phenomenon. Read on to learn more about the bomb cyclone UPSC topic.

What is Bomb Cyclone?

Meteorologists use the term bomb cyclone to describe a mid-latitude cyclone that is quickly intensifying. A massive winter storm is battering the shore, bringing with it strong winds, water, ice, and snow. It’s caused by a combination of rapidly dropping pressure and extreme cold.

This storm is the most powerful on the east coast in recorded history. The storm is known as a bomb cyclone, a dramatic moniker for what transpires when the storm intensifies explosively while the pressure drops.

How is a Bomb Cyclone Formed?

The creation of Bomb Cyclones has been attributed to a variety of factors. Baroclinic instability has been proposed as the primary mechanism for its creation. However, even this fundamental mechanism has been the topic of discussion among scientists, since several case studies have demonstrated it differently.

There are several other things to consider, such as:

# Both upstream and downstream of the cyclone’s surface, deep atmospheric temperature frontogenic processes occur.

# The impact of the air-sea interaction

# The release of latent heat

Bomb Cyclone Regions

# The Northwest Pacific

# The Northern region of the Atlantic Ocean

# The Southwest Pacific

# The Southern region of the  Atlantic Ocean.

There is conjecture that, as a result of climate change, additional locations will be vulnerable to bomb cyclones.

The frequency of explosive cyclones is observed to be higher north of the Atlantic Gulf Stream, in the Western Pacific, and in the Indian Ocean. It is mostly found along Australia’s eastern seaboard in the Southern Hemisphere.

South of 50°S, exponentially deepening cyclones frequently migrate equatorward, in contradiction to the poleward migration of most Northern Hemisphere bombs.
