In the fall of 2005, the Amazon River suddenly dried up (photo attached). At the same time, a little to the north, in the Caribbean, the number of tropical cyclones increased abnormally (the graph is attached). In addition, the formation of tropical cyclones continued until January 2006, see cyclones Delta and Zeta (map attached). It happened in one geographic region. I think these anomalies may have a common cause. I analyzed the gravitational field, which can form an anomaly of high atmospheric pressure in the region. Maybe there are other ideas? In 2010, the drought in the Amazon was not accompanied by an anomaly of tropical cyclogenesis.
For drought, water (over)use and (mis)management must be considered as much as precipitation variations Article When is a drought a drought?

Dear Ilan Kelman, Thanks to you, we managed to see that in 2005 the latitudinal zone of high pressure in the tropical zone of the Atlantic became wider (attached the map). This confirms the availability of favorable conditions for tropical cyclogenesis. In my picture (Persipstation) you can see the drought in Central America and you can see how the cyclones have increased rainfall in the Caribbean Sea.
Yes, the Sahara dust interferes with the formation of rain clouds. The hurricane weather for Florida on the FOX TV weather channel was tracking the Sahara dust and showed how it stops the creation of hurricanes--it is like the perfect "butterfly effect" a cow eats a native grass in the desert of Morocco that causes the soil to get airborne that travels across the Atlantic to stop the rain in the Amazon.

The other issue is cutting down the trees that create the rain clouds in the Amazon, that are the host plants for the Pseudomonas bacteria--the organism that creates the "Cloud Forests". See https://www.discovermagazine.com/planet-earth/does-rain-come-from-life-in-the-clouds
