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. It is mostly used 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).

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.).
The global models that MetService uses generally provide reliable forecasts of weather features, like highs and lows, over forecast periods of several days; however, they are less effective at predicting small-scale weather features like sea breezes and localised showers. Such features are often strongly affected by the local geography, which ...
NIWA and MetService are both government organizations that produce weather forecasts. NIWA was previously part of the MetService until 1992. NIWA was previously part of the MetService until 1992. [ 5 ] [ 6 ] In 2009, they signed a memorandum of understanding to work more closely together. [ 34 ]
A large range between 1 and 10 day forecasts are available, delivering 4 and 40 images, respectively, spaced at +6 hour intervals, beginning with the forecast time. These weather forecast charts are generated by software written and maintained by James McGregor. The data used is obtained from the United States National Weather Service. These ...
This weather circulates the southern seas largely unimpeded by land until it reaches the Southern Alps. The humid westerly wind is forced up over the mountains, at cooler elevation water condenses and falls as snow or rain. This orographic rain explains the huge difference in conditions between the wet west and dry east of the South Island. [4]
MetService issues a red heavy rain warning for North Otago, Dunedin and the coastal Clutha District. [308] A state of emergency is declared in Dunedin in response to heavy rainfall and flooding. Residents in low-lying suburbs are told to evacuate. [309] 4 October: A state of emergency is declared in the Clutha District due to heavy rainfall and ...
