34. REASONS FOR A SLOWLY
DEVELOPING SEASON

35. 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

36. 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.
