Explanation:

Doppler Weather Radar

• Based on Doppler principle the radar is designed to improve precision in long-range weather forecasting and surveillance using a parabolic dish antenna and a foam sandwich spherical radome.
• DWR has the equipment to measure rainfall intensity, wind shear and velocity and locate a storm centre and the direction of a tornado or gust front.
• Doppler radar can be divided into several different categories according to the wavelength which are L,S,C,X,K.
• X-band radar is used to detect thunderstorms and lightning.
• C-band radars is best used for short range weather observation and guides at the time of cyclone tracking.
• S band radars are useful for near and far range weather observation.

Hence both statements are correct.
