REASONS FOR A SLOWLY DEVELOPING SEASON

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.
