Description
This animation is derived from radar
observations from the Upton,
NY National Weather Service office focused on the New York City metropolitan
area. The data are available courtesy of the National
Weather Service via their NOAAport
data transmission system. The NOAAport system used for this project
was developed by Planetary Data,
Inc. The region corresponding to most of 4 km nest of the Deep
Thunder forecasts is shown. Several derived reflectivity, precipitation
and velocity fields are available on the NOAAport system after extensive
sampling, binning and compression. As an interim product, two of
the variables, composite reflectivity and total (liquid) precipitation
have been processed via a modified version of the GEMPAK/N-AWIPS
software, in order to be presented in this animation. This product
will eventually be replaced with more sophisticated type of visualization
better able to illustrate the characteristics of these data.
The animation is a montage of reflectivity on the left and precipitation
on the right, color mapped according to the legend at the left of each
frame. Each frame is overlaid with maps of coastlines, state and
county boundaries as well as major roads. Nominally, a new image
is provided five to 15 minutes as presented in this animation. During
periods of "severe" weather, the update rate will be more frequent.
The time associated with each image is shown by a date and time stamp at
the top and bottom, where time is in GMT. This animation shows only
the previous 12 hours of data at the time the animation was generated.
The frames in this animation, in general, will cover the period of recent
Deep Thunder forecasts illustrated at this site.
Instructions
An animation (compressed as an MPEG-1 video) is shown above with about
15 minutes of time between each frame. Depending on your connection
speed and that of your computer, the animation may take a few minutes to
load and decompress in your browser. The progress of that process
is shown until it is completed. When it is completed, the animation
will play. There are VCR-like controls under the animation to enable
you to stop playback, play forward or backward, or step through the frames
one at a time. If you are having problems viewing or
interacting with this animation, make sure your browser has Java and Javascript
enabled. If you are still having difficulty, you can download
the mpeg file directly.
