SEPTEMBER 9th“2013 SEASON MAY GO IN THE RECORD BOOKS AS A “DUD””
REASONS FOR A SLOWLY DEVELOPING SEASON • "A large area of high pressure over the central Atlantic has been very strong and very good at driving dry air southward into the tropics into September." • Generally it is easier for tropical storms to form and tropical storms to streng-then into hurricanes when an un-obstructed supply of moisture available
REASONS FOR A SLOWLY DEVELOPING SEASON • Frequent surges of wind shear [disruptive winds at mid-levels of the atmosphere] have occurred during the 2013 season. • Wind shear tends to disrupt the circulation around a developing system, shearing off the top of the system or causing it to be very lop-sided.
