The center is tasked with weather forecasting, issuing early warnings, and collaborating with other international meteorology institutions to employ the latest technologies. [3] [4] [5] In addition to its meteorological services, the center is responsible for cloud seeding [6] to increase the rate of precipitation in United Arab Emirates [7] [8]
Weather radar, also called weather surveillance radar ( WSR) and Doppler weather radar, is a type of radar used to locate precipitation, calculate its motion, and estimate its type (rain, snow, hail etc.). Modern weather radars are mostly pulse-Doppler radars, capable of detecting the motion of rain droplets in addition to the intensity of the ...
The United Arab Emirates is one of the first countries in the Persian Gulf region to use cloud seeding technology. UAE scientists use cloud seeding technology to supplement the country's water insecurity, which stems from the extremely hot climate. [2] They use weather radars to continuously monitor the atmosphere of the country. [3]
The scale of dBZ values can be seen along the bottom of the image. Decibel relative to Z, or dBZ, is a logarithmic dimensionless technical unit used in radar, mostly in weather radar, to compare the equivalent reflectivity factor (Z) of a remote object (in mm 6 per m 3) to the return of a droplet of rain with a diameter of 1 mm (1 mm 6 per m 3).

Doppler effect. The emitted signal toward the car is reflected back with a variation of frequency that depends on the speed away/toward the radar (160 km/h). This is only a component of the real speed (170 km/h). The Doppler effect (or Doppler shift), named after Austrian physicist Christian Doppler who proposed it in 1842, is the difference ...
The frequency selection of weather radar is a performance compromise between precipitation reflectivity and attenuation due to atmospheric water vapor. Some weather radars uses doppler shift to measure wind speeds and dual-polarization for identification of types of precipitations. [3] [4] Weather radar; Wind profilers; Millimetre cloud radar ...
A storm hit the United Arab Emirates and Oman this week bringing record rainfall that flooded highways, inundated houses, grid-locked traffic and trapped people in their homes. At least 20 people ...
The United Arab Emirates Research Program for Rain Enhancement Science ( UAEREP) is a global research initiative offering a grant of US$5 million over a three-year period to be shared by up to five winning research projects in the field of rain enhancement. The cloud-seeding operations were initiated in the late 1990s in the UAE.
