Tropical Storms – Roundup of Tropical Storms:
There are no current tropical storms.
The Amazon – Scientists and the media have documented deepening drought in the Amazon basin. But a new study finds that flood events are significantly intensifying too, becoming five times more common over the last century. The effect is caused by a combination of factors, including an increase in strength of the Walker circulation – an ocean-driven pattern of air circulation that carries warm moist air from the tropical Atlantic across South America towards the Pacific, resulting in Amazon precipitation. Human-driven climate change is a major contributing factor to this increased Amazon basin flooding. Intensifying flood events result in lives and property lost, and significant harm to croplands, pastures and livestock.
