If any tropical storms and subsequent
hurricanes form before the season ends on Nov. 30, they will be classified using the Greek alphabet, beginning with Alpha.
This is because terrestrial
hurricanes form when an inflow of air along the ocean surface sops up moisture and rises in a halo of updrafts to create towering columns of rain clouds.
During this month, the sea temperatures are at their highest and the probability
of hurricanes forming in the Atlantic and travelling over to the Caribbean is relatively high.
They compared their storm surge index to changes in global surface temperature, to temperatures in the Main Development Region (MDR; a part of the Atlantic Ocean where
most hurricanes form), and to MDR warming relative to the tropical mean temperatures (rMDR).
«If you lack choppy waters or a frictional surface that allows wind to converge, which is
how hurricanes form on Earth, how can you possibly get something that looks similar on a gas giant?»
They found that
future hurricanes formed further east in the tropical Atlantic, as that area had warmed sufficiently to provide enough heat and moisture to power them.
According to Brian McNoldy of the Capital Weather Gang, the median date for when the
first hurricane forms is Aug. 16.
Harvey is also a
powerful hurricane forming in one of the most hurricane - friendly regions of the world at the peak of hurricane season.
«But what's amazing is if you actually looked at the trends in the Atlantic Ocean — the region where
hurricanes form from five north to 20 north — from Africa over to the United States, it's actually cooling down.
It seems like that shallow south flowing water must be warm (it's the portion of the Gulf stream that's turned around and headed back south), and it's headed right
where hurricanes form.
The detailed, real - time wind measurements could help scientists to better understand
how hurricanes form and provide information that meteorologists can use to pinpoint landfall earlier, giving people more time to prepare and evacuate.
The recent increases in activity are linked, in part, to higher sea surface temperatures in the region that Atlantic
hurricanes form in and move through.
These hurricanes form from a tropical depression or tropical wave that passes through or near that chain of islands, and then eventually strengthens into a named system (finally becoming a hurricane at some point) in the mid-Atlantic.
Eyes in the Sky Of course, even the best radars can not see over mountains or out into the oceans, where
hurricanes form.
As a result, we've had these category 4 and 5
hurricanes forming in that region.»
As
the hurricane forms, deeper water in the ocean is driven to the surface.
«What happens in the early part of the season is generally not a good predictor of the second half of the season, which is when the majority of hurricanes and major
hurricanes form.
Every year in August and September,
hurricanes form over the Atlantic.
Klotzbach noted that since 2005, 22 major
hurricanes formed in the Atlantic, yet none of them made landfall in the U.S. as major hurricanes.
Klotzbach said the area where most tropical storms and
hurricanes form had the driest mid-to-lower atmospheric conditions during the Aug. 1 to Sept. 25 period since reliable records began in 1970.
The spiraling wind pattern helps
the hurricane form.
This is false,
a hurricane forms from a large mass of LOW pressure.
And since the 1980s, there has been an increase in the number and strength of Category 4 and 5
hurricanes forming in the Atlantic Ocean, even though few have made landfall.
If a tropical storm or
hurricane forms, track it on weather apps like Storm Shield, which allows folks to save multiple locations, making it easy to check the weather for your home and your vacation spot, says Meyers.
Weather apps like Storm Shield, which is capable of saving multiple locations, can also come in handy if and when a tropical storm or
hurricane forms.
If you have purchased travel insurance at least 24 hours before
a hurricane forms, you can typically have your non-refundable travel costs reimbursed if you are forced to cancel your plans.
