The development of modern radar started in 1886, when German physicist Heinrich Hertz showed that radio waves could be reflected from solid objects. In 1904, another German, Huelsmeyer, was the first to build a simple ship detection device, successfully detecting a ship in dense fog. In the pre-war period (the 1930s), many nations were working on radar devices. A major advance occurred once systems were developed that allowed short ‘pulses’ of radio energy to be generated, allowing the range of the object to be determined by timing the pulses.
During October 2014, MetService Meteorologist John Law spent five days in Antarctica. We thought you would be interested to see Antarctica through John's eyes, so he kept a blog to report back on what he was up to each day!
Victoria University of Wellington will offer the country’s first Master’s degree in meteorology, in partnership with New Zealand’s official weather forecaster MetService.
MetService’s long-range weather radar, situated near Kaeo in Northland, officially commenced operations on Monday 28 July 2014, with early imagery from the radar enabling MetService forecasters to provide very valuable information to Civil Defence and the public ahead of the June storms experienced in the region that year.
