Currently in the Atlantic-August 31st, 2022

The weather, currently.

Where's the "Bermuda High"?

What kind of "peak" hurricane season map is this? Sure, there are a couple of tropical lows in the Atlantic east of the Caribbean. But where's the "Bermuda High"? That "H" of 1018 (millibars) near Bermuda is incredibly weak for this time of year. The strongest "H" on the map is in the upper right of the picture, of 1027 millibars. That's closer to Ireland than Bermuda!

Why is that important? That Bermuda High helps steer tropical systems from east to west-from the disturbances off Africa to either the Caribbean or western Atlantic. No steering=slow movement. It breaks up the whole pattern.

How is that going to change in the next week? Not much-see below:

An even weaker "Bermuda High" in a week

The blue colors indicate lower pressures than "normal" in much of the tropical Atlantic. Obvious. And the redder colors show higher than "normal" pressures through much of what is called the MDR (main development region). That's where many of history's worst hurricanes have tracked (called Cabo Verde-formerly Cape Verde storms). That is an unfavorable pressure pattern overall for the types of hurricanes we often see in the peak month of September.

Why is this pattern here? Perhaps it is related to the image below: ocean temperatures compared to "normal".

Extra warm in North Atlantic. Less "gradient" from north to south

Hard to get a "normal" peak hurricane season like this. And look at the wind shear map below:

Unusually high shear in the heart of the tropics

It's a little hard to see, but those red lines show areas with unfavorable wind patterns for tropical formation. That's the "heart" of the tropics!

Hard to see hurricane season getting active until these patterns change.

I'll continue doing tropical updates, often focusing on things you might not see elsewhere. And we'll also write about how Climate Change is influencing individual storms and tropical weather in general.

What you need to know, currently.

If you’ve never eaten a breadfruit, now is the perfect time!

According to reporting by Smithsonian magazine, the fruit could play a role in addressing global hunger as well as food security adaptation amid global warming and climate change.

Breadfruit is very versatile, as it can be dried and ground into flour –– its trees provide abundant shade for humans and wildlife alike, and it’s been used to treat various skin ailments. The perennial custard-y fruit is also very rich in nutrients and requires less labor, water and fertilizer than annual crops.

“I really think it has a lot of potential to help people, especially in the tropics, where 80 percent of the world’s hungry live,” Diane Ragone, founder of the Breadfruit Institute, told Smithsonian magazine in 2009. “It’s low-labor and low-input; much easier to grow than things like rice and corn. And because it’s a tree, the environmental benefits are huge compared to a field crop.”

Past research has found that yields of staple crops like corn, wheat and rice may decline due to climate change, particularly in areas close to the equator. The breadfruit, on the other hand, is more resilient to rising temperatures. In conjunction with other food security adaptations and solutions, this tropical fruit could make a real difference.
