Extreme weather caused by concurrent cyclone, front and thunderstorm occurrences

Area of Science:

• Meteorology
• Climatology
• Atmospheric Science

Background:

• Extreme weather events, including severe precipitation and high winds, are significant global concerns.
• Individual meteorological phenomena like cyclones, fronts, and thunderstorms are well-studied.
• The combined influence of these phenomena on extreme weather remains underexplored, representing a knowledge gap.

Purpose of the Study:

• To systematically analyze the combined effects of cyclones, fronts, and thunderstorms on extreme weather.
• To identify specific storm combinations that lead to extreme precipitation and wind events globally.
• To enhance understanding of the interplay between different meteorological phenomena in extreme weather causation.

Main Methods:

• A systematic analysis of seven distinct storm combination types was conducted.
• The study examined the co-occurrence of cyclones, fronts, and thunderstorms.
• Regional data was analyzed to correlate storm combinations with extreme precipitation and wind events.

Main Results:

• The research identified storm combinations most frequently associated with extreme weather globally.
• A triple storm type, involving concurrent cyclones, fronts, and thunderstorms, showed the highest risk.
• This combination was strongly linked to extreme precipitation and extreme wind speeds worldwide.

Conclusions:

• Concurrent meteorological phenomena play a crucial role in driving extreme weather events.
• Understanding these combined influences is vital for improving extreme weather prediction and mitigation.
• The study provides new insights into the complex relationships between cyclones, fronts, and thunderstorms.
