Olivia Photo gallery
On 24 and 25 September 1994 Dr. Peter Black took a remarkable
set of slides in Eastern Pacific Hurricane Olivia. On the 24th
Olvia's central pressure was steady at 949 hPa and the maximum
flight-level winds were 120 kt. On the 25th the storm had intensified
to 925 hPa, but the sea-level pressure rose by more than 10 hPa
during the 4 h that the P-3s were there. The storm moved from
WNW 16N 118W on the 24th to 19N 120W on the 25th. These images
illustrate important aspects of tropical-cyclone eye dynamics:
- View of Olivia's eyewall with the P-3's wing in the foreground.
- Inclined convective rolls along the inner edge of the eyewall wind maximum.
- Virga cascading down the
inner edge of the eye.
- Low clouds in Olivia's eye
on 24 September showing the sea surface visible through breaks
in the undercast.
- Low clouds in the eye on 25 September
showing the unbroken overcast due to moistening of the
eye as Olivia filled.
