How far can a Doppler radar detect precipitation?
The National Weather Service's 148 WSR-88D Doppler radars can detect most precipitation within approximately 90 mi of the radar, and intense rain or snow within approximately 155 mi. However, light rain, light snow, or drizzle from shallow cloud weather systems are not necessarily detected.
When do birds return to radar?
Echoes from migrating birds regularly appear during nighttime hours between late February and late May, and again from August through early November. Return from insects is sometimes apparent during July and August. The apparent intensity and areal coverage of these features is partly dependent on radio propagation conditions, but they usually appear within 30 miles of the radar and produce reflectivities of <30 dBZ.
Why is TDWR bad?
The most serious drawback to using the TDWRs is the attenuation of the signal due to heavy precipitation falling near the radar. Since the TDWRs use the shorter 5 cm wavelength, which is closer to the size of a raindrop than the 10 cm wavelength used by the traditional WSR-88Ds, the TDWR beam is more easily absorbed and scattered away by precipitation. This attenuation means that the radar cannot "see" very far through heavy rain. It is often the case that a TDWR will completely miss seeing tornado signatures when there is heavy rain falling between the radar and the tornado. Hail causes even more trouble. Thus, it is best to use the TDWR in conjunction with the traditional WSR-88D radar to insure nothing is missed.
How is precipitation intensity measured?
Precipitation intensity is measured by a ground-based radar that bounces radar waves off of precipitation . The Local Radar base reflectivity product is a display of echo intensity (reflectivity) measured in dBZ (decibels). "Reflectivity" is the amount of transmitted power returned to the radar receiver after hitting precipitation, compared to a reference power density at a distance of 1 meter from the radar antenna. Base reflectivity images are available at several different elevation angles (tilts) of the antenna; the base reflectivity image currently available on this website is from the lowest "tilt" angle (0.5°).
What is Nexrad radar?
NEXRAD ( Nex t Generation Rad ar) can measure both precipitation and wind. The radar emits a short pulse of energy, and if the pulse strike an object (raindrop, snowflake, bug, bird, etc), the radar waves are scattered in all directions. A small portion of that scattered energy is directed back toward the radar.
What is the Doppler effect?
The ability to detect the "shift in the frequency" of the pulse of energy makes NEXRAD a Doppler radar. The frequency 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.
Is it harder to detect a mesocyclone?
If the thunderstorm is moving rapidly toward or away from you, the mesocyclone may be harder to detect. In these cases, it is better to subtract off the mean velocity of the storm center, and look at the Storm Relative Mean Radial Velocity.
What is a weatherbridge?
The WeatherBridge is a device that allows your weather station to send data to Weather Underground without the need for a computer. WeatherBridge works with many different weather stations.
Does the Weatherbridge work with the Ubiquiti Aircam?

The WeatherBridge and AirBridge work with Weather Station AND Webcams. The MeteoBridge is designed to work most easily with Ubiquiti AirCam.
What is a Personal Weather Station?
A personal weather station is a set of weather measuring instruments that you can install at your own home or business. The number of instruments can vary, but most personal weather stations include instruments to measure temperature, relative humidity, pressure, rain fall, and wind speed and direction. Scroll down to learn more about these sensors and how a personal weather station works.
What is the purpose of a hygrometer?
Relative Humidity: Hygrometer. A capacitor type of hygrometer is usually used to measure relative humidity. The sensor has a dielectric polymer layer that absorbs water molecules from the air through a thin metal electrode. This causes a change in capacitance and signifies a proportional change in relative humidity.
How does a cup anemometer work?
Cup anemometer with separate wind van e - Uses three cups to measure wind speed, while a wind vane measures wind direction. The vane always points in the direction that the wind is coming from and reports an analog voltage signal directly proportional to the azimuth angle. As for wind speed, the 3 cups are used so one cup is always at a 45 degree angle to the wind. With this configuration, there is not one cup that has no wind, as was the case with a four cup anemometer. The voltage output needs to be scaled to the actual wind speed, based on the size of the cups and overall diameter of rotation.
Why is humidity sensor mounted next to temperature sensor?
The humidity sensor is most often mounted next to the temperature sensor to ensure a correlation between temperature and relative humidity , which are then used to calculate dew point.
What is the best way to measure wind speed?
Sonic anemometer - Uses ultrasonic sound waves to measure wind speed based on the time of flight of sonic pulses between pairs of transducers and can measure wind velocity in 3 dimensional flow. These sensors can take measurements up to 20 Hz and are thus ideal for measuring turbulence.
How are thermocouples made?
Thermocouples are made by joining 2 different metals to create a voltage when temperature differs from the reference temperature, based on the electromagnetic force generated at the junction of the different metals. RTD Probes (Resistance Temperature Detector Probes) are comprised of pure metal (usually platinum).
