Doppler Radar Map for New Jersey
This is the latest Doppler Radar Map for New
Jersey from the National Weather Service. This image is generated at
the National Weather Service's Mount Holly, New Jersey station by
NEXRAD (Next Generation Radar) obtains weather
information (precipitation and wind) based upon returned energy. The
radar emits a burst of energy (green). If the energy strikes an object
(rain drop, bug, bird, etc), the energy is scattered in all directions
(blue). A small fraction of that scattered energy is directed back
toward the radar. This reflected signal is then received by the radar
during its listening period. Computers analyze the strength of the
returned pulse, time it took to travel to the object and back, and
phase shift of the pulse. This process of emitting a signal, listening
for any returned signal, then emitting the next signal, takes place
very fast, up to around 1300 times each second.
NEXRAD spends the vast amount of time "listening"
for returning signals it sent. When the time of all the pulses each
hour are totaled (the time the radar is actually transmitting), the
radar is "on" for about 7 seconds each hour. The remaining 59 minutes
and 53 seconds are spent listening for any returned signals. The
ability to detect the "shift in the phase" of the pulse of energy makes
NEXRAD a Doppler radar. The phase of the returning signal typically
changes based upon the motion of the raindrops (or bugs, dust, etc.).
This Doppler effect was named after the Austrian
physicist, Christian Doppler, who discovered it. You have most likely
experienced the "Doppler effect" around trains. As a train passes your
location, you may have noticed the pitch in the train's whistle
changing from high to low. As the train approaches, the sound waves
that make up the whistle are compressed making the pitch higher than if
the train was stationary. Likewise, as the train moves away from you,
the sound waves are stretched, lowering the pitch of the whistle. The
faster the train moves, the greater the change in the whistle's pitch
as it passes your location. The same effect takes place in the
atmosphere as a pulse of energy from NEXRAD strikes an object and is
reflected back toward the radar. The radar's computers measure the
phase change of the reflected pulse of energy which then convert that
change to a velocity of the object, either toward or from the radar.
Information on the movement of objects either toward or away from the
radar can be used to estimate the speed of the wind. This ability to
"see" the wind is what enables the National Weather Service to detect
the formation of tornados which, in turn, allows them to issue tornado
warnings with more advanced notice.
