NASA ’s Terra satellite lately captured this arresting exposure of Saharan dust waft over the Atlantic sea . It ’s one of several eruption this summertime that some speculate may be kick in to this year ’s comparatively peaceful storm season .
Asnotedby Kimberly Miller at the Palm Beach Post , Saharan dust is the unattackable it has been in a decade , but it ’s not immediately obvious if the dust is among the most important give factor to the suppression of tropical storms and hurricane .
Jason Dunion , a research meteorologist for the National Oceanic and Atmospheric Administration ’s hurricane sectionalisation in Miami , told Miller that about “ a international mile up into the surface aura , what is commonly really tropical and juicy , has about half the moisture , which makes it unmanageable for thunderstorms to form . ” And indeed , there may be a relationship between Atlantic tropic cyclone body process and African rubble outbreaks .
That said , there are other important factor to debate . For example , El Niño is currently causing dry air conditions , hard lead shear , and below average ocean - aerofoil conditions in the Atlantic , which are n’t conducive for tropic storms .

functionary at the National Hurricane Center are not factoring the Saharan dust for their forecasting , articulate it ’s just too irregular .
“ It ’s pulses of dust , so it ’s now always there , and it can be very discreet , ” noted a NHC science official to Miller . “ It would be nice if we could continue the remainder of the hurricane season being slow , but all we can say is the next five twenty-four hours is expected to be gracious and quiet . ”
