DopplerWeaherRadarinternshipreport
说明： 新一代多普勒天气雷达系统基于对气象和自然灾害的准确预警而产生的。主要应用在于对灾害性天气，特别是与风害相伴随的灾害性天气的监测和预警。它还可以进行较大范围降水的定量估测，获取降水和降水云体的风场结构。(A new generation of Doppler weather radar system is based on the accuracy of weather and natural disasters, early warning generated. Main application is on the severe weather, especially wind damage accompanying the severe weather monitoring and early warning. It can also be a larger range of quantitative estimates of precipitation, precipitation and precipitation cloud body to obtain the wind field structure.)
