Climate Change and Tropical Storms in 2024

November 22, 2024

Recent climate events have raised concerns about tropical storms and the West Pacific has seen an unusual cluster of typhoons. The Atlantic has experienced powerful hurricanes., which occurrences coincide with discussions on climate financing at COP29 in Azerbaijan. The Philippines faced its sixth deadly typhoon this month and the U.S. is recovering from two intense hurricanes.

Impact of Warmer Sea Temperatures

Warmer sea surface temperatures are a factor. Global warming increases evaporation rates, which process fuels tropical storms. Consequently, storms exhibit stronger winds and heavier rainfall. The Intergovernmental Panel on Climate Change (IPCC) confirmed that global warming intensifies storms.

Storm Frequency vs. Intensity

Some scientists argue climate change may decrease storm numbers. This trend is particularly noted in late-season months, like October and November. This relationship requires further study.

Recent Typhoon Events

Supertyphoon Man-Yi recently struck the Philippines. The storm forced mass evacuations, which contributed to over 160 fatalities since October. Experts caution against directly linking this typhoon to climate change. Other atmospheric factors may also play a role.

Atlantic Hurricane Trends

Record ocean temperatures have impacted Atlantic hurricanes. Climate Central reported a rise in average hurricane wind speeds. Since 2019, speeds have increased by about 18 miles per hour (29 kph). This warming has resulted in three storms reaching Category 5 strength. Hurricanes Helene and Milton, which hit Florida, exemplify this trend.

Future Research Needs

While there is high confidence in the link between climate change and storm intensity, more research is essential. About the frequency and seasonality of storms remains a key area of inquiry. Scientists aim to clarify how climate change alters these patterns.

Important Facts for Exams:
COP29: COP29 refers to the 29th Conference of the Parties. It focuses on climate change negotiations. This year’s event took place in Azerbaijan, addressing global climate financing issues.
Supertyphoon Man-Yi: Supertyphoon Man-Yi recently struck the Philippines. It caused mass evacuations and important fatalities. Over 160 people have died since October due to this severe weather event.
IPCC: The Intergovernmental Panel on Climate Change is a scientific body. It assesses climate change impacts and provides reports. The IPCC confirmed that global warming intensifies storm severity and frequency.
Sub-tropical Ridge: The sub-tropical ridge is a high-pressure system. It influences weather patterns near the equator. Changes in this system can affect tropical storm activity and intensity.
