United
States National Oceanographic and Atmospheric
Administration (NOAA) pilot chart and ship drift surface
current data was used in the development of Visual
Passage Planner 2 (VPP2). This data includes more than
one hundred years (1850-1974) of world wide weather
observations at both 1-degree and 5-degree
resolution. The data includes.
- Wind Roses
- Current Roses
- Mean Wind Speeds
- % Gales
- Wave Heights
- Sea/Air Temperatures
- Dew Points
- Atmospheric
Pressures
- % Light/Heavy Icing
Data for the entire
world (75°N Lat. to 75°S Lat) for all 12 months is
included.
Weather data can be
viewed in VPP2 in many ways. The 'Weather Bar'
(see the left side of the screen shots) provides continuous
weather data information as you move the cursor over the
screen. Various graphical Weather Overlays are also available.
The screen shots at
left show:
(Top) Mean Wave Heights
for the month of April overlaid on top of the textured
map.
(Bottom) Mean current
direction and strength for the month of August (1-degree
