Meteorological Analysis
|
Arlene originated from a complex non-tropical reaction. On June 8th an upper
low formed along a cold front in the Atlantic. A tropical wave then interacted
with the upper level low and caused a low level circulation to form, convection
increased with the upper low. On the 10th the upper low moved into an area
of convection and the upper level vorticity translated down to the surface
causing a low level center to form. The low level center then organized and
became a tropical depression on the 11th, about 465 nm SE of Bermuda. The
depression initially drifted north through a weakness in the subtropical ridge
and strengthened into tropical storm Arlene on the 12th. Arlene reached its
maximum strength of 60 mph with a pressure of 1006 mb on the 13th. Shear
then began to cause Arlene to weaken as Arlene moved erratically due to
a lack of steering currents. A trough then began to accelerate Arlene to the NE
on the 15th, and by the 17th Arlene passed within 100 nm of Bermuda. Arlene
had little impact on the island. Arlene then continued to weaken over cooler
waters and was downgraded into a tropical depression on the 17th. Arlene
dissipated ahead of a front on the 18th.
