ITHACA — For the first time,
researchers here are using maps that rely on radar to forecast night-time
clouds of migratory birds and to track flights in near-real-time.
Scientists with the Cornell Lab
of Ornithology and the University of Oxford in England made the breakthrough —
processing weather radar data to produce maps that visualize migration on the
Cornell Lab’s BirdCast website (birdcast.info).
One map shows an
animated visualization that tracks migration in
near-real-time. Cornell lab postdoctoral associate Adriaan Dokter designed an
algorithm to rapidly estimate the intensity and flight directions of migrating
birds detected by the weather radar network. The system processes incoming
radar data continuously and updates the animated map every 10 minutes.
Another map forecasts migration
three days ahead. The color-coded displays combine projected weather conditions
and bird movements to show where and when the most intense migrations are
expected.
