CAPPI(Constant Altitude Plan Position Indicator) monitoring
by the WR-2100

Data from the identical altitude is to be Extracted and monitored, suitable for observing the development of a cumulonimbus. (Altitude:1~9km)

(Jul 6, 2013 19:03-19:05)

On CAPPI observation, horizontal cross-section scans of a cumulonimbus are conducted at the equal altitudes. The altitude of a developed cumulonimbus top may exceed 10 km. Precipitation can be observed at higher altitude in a greatly developed cumulonimbus.

RHI(Range Height Indicator) monitoring
by the WR-2100

Vertical cross-section scan on a cumulonimbus is conducted, suitable for observing the development of a cumulonimbus.

( Aug 6, 2013 18:30-18:59)

On RHI observation, vertical cross-section scans of a cumulonimbus are conducted, hence easily grasping development status of a cumulonimbus. This case example clearly shows the active up-and-down movement of nimbus.

Doppler velocity monitoring
by the WR-2100

Suitable for monitoring nimbus movement velocity and wind field

Doppler velocity monitoring

(Aug 6, 2013 18:30-18:59)

On Doppler observation, by monitoring Doppler velocity of nimbus, moving velocity of nimbus, namely, wind speed and direction, can be computed. In this case example, warm colours indicate the winds that move away from the Radar antenna, while cold colours indicate the winds that move towards the Radar antenna. The arrow lengths and direction indicate the wind speed and direction, respectively.

PPI(Plan Position Indicator) monitoring
by the WR-2100

Monitoring is to be conducted at fixated elevation angle, suitable for rainfall amount on the ground and low-level wind shear observation.

PPI monitoring

(Rainfall amount observation / Jun 26, 2013 14:00-15:00)

(Precipitation intensity observation / Nov 13, 2012, 17:26)

The antenna is rotated while fixating its elevation angle.
PPI observation at low elevation angle generates rainfall amount on the ground. Also, when the rainfall amount data is accumulated for the duration of 1 hour, accumulated rainfall amount for 1 hour can be calculated.
Also, by analysing the Doppler velocity obtained by PPI observation at low elevation angle, low-level wind shear can be obtained.
