The world's first televised weather forecasts, including the use of weather maps, were experimentally broadcast by the BBC in November 1936. [31] This was brought into practice in 1949, after World War II. [31] George Cowling gave the first weather forecast while being televised in front of the map in 1954.
The economy of Namibia has a modern market sector, which produces most of the country's wealth, and a traditional subsistence sector. Although the majority of the population engages in subsistence agriculture and herding, Namibia has more than 200,000 skilled workers and a considerable number of well-trained professionals and managerials.
The value of Zambian currency dropped following redenomination; the exchange rate was 22 kwacha to one U.S. dollar in April 2021. After the 2021 Zambian general election saw a defeat for Edgar Lungu , the currency's depreciation was reversed; as of 27 August 2021 [update] one U.S. dollar was exchanged for about 16 kwacha. [ 5 ]
The dollar replaced the South African rand, which had been the country's currency while it was under South African rule as South-West Africa from 1920 until 1990, at par. . The rand is still legal tender, as the Namibian dollar is linked to the South African rand and can be exchanged on a one-to-one basis loca

Weather reconnaissance aircraft, such as this WP-3D Orion, provide data that is then used in numerical weather forecasts.. The atmosphere is a fluid.As such, the idea of numerical weather prediction is to sample the state of the fluid at a given time and use the equations of fluid dynamics and thermodynamics to estimate the state of the fluid at some time in the future.
The Storm Prediction Center (SPC) is a US government agency that is part of the National Centers for Environmental Prediction (NCEP), operating under the control of the National Weather Service (NWS), [1] which in turn is part of the National Oceanic and Atmospheric Administration (NOAA) of the United States Department of Commerce (DoC).
Graphical 12-hour forecast output from RUC2. The Rapid Update Cycle (RUC) was an American atmospheric prediction system that consisted primarily of a numerical forecast model and an analysis system to initialize the model. The first operational implementation was created in 1994, with 60km resolution and a 3-hour cycle.
