The impact of external influences on the tropical Atlantic climate: New study reveals important connections between ocean temperatures, precipitation and hurricane activity.

The role of the tropical Atlantic in hurricane formation and rainfall in the Sahel is the conclusion of a new study published by researchers. The study shows that the relationship between tropical Atlantic surface temperatures, Sahel rainfall and hurricane activity is important. This connection has been controversial until now due to various uncertainties in models and observations.

The research results indicate that the climate in the tropical Atlantic has been strongly influenced by radiation-related disturbances resulting from anthropogenic emissions and volcanic aerosols since 1950. Especially since 1950, when anthropogenic aerosol forcing is high, correlations have emerged between surface temperatures and Atlantic hurricane formation and Sahel precipitation in response to radiative forcing.

The study's findings suggest that the surface temperature gradient in the tropical Atlantic is a stronger determinant of tropical impacts than surface temperatures across the North Atlantic as a whole. This is because the gradient across local atmospheric circulations is more strongly associated with tropical impacts.

The research also shows that Atlantic hurricane activity and variations in Sahel precipitation can be predicted by radiative forcing from anthropogenic emissions and volcanism. However, more accurate predictions are limited due to the signal-to-noise paradox and uncertainties in future climate impacts.

The study highlights the importance of the tropical Atlantic for understanding climate variability and weather phenomena. The impact of anthropogenic influences on the tropical Atlantic has significant impacts on the climate and precipitation in the Sahel, which can help make more accurate predictions for the future.

The research findings highlight the need for further investigation and research to better understand the relationships between the tropical Atlantic, hurricane activity and Sahel rainfall. This understanding can help develop measures to better manage the impacts of climate change on these regions.
