A meteorologist is a scientist who studies and works in the field of meteorology aiming to understand or predict Earth's atmospheric phenomena including the weather. [1] Those who study meteorological phenomena are meteorologists in research, while those using mathematical models and knowledge to prepare daily weather forecasts are called weather forecasters or operational meteorologists.
These factors can each influence the safety of marine transit. Consequently, a variety of codes have been established to efficiently transmit detailed marine weather forecasts to vessel pilots via radio, for example the MAFOR (marine forecast). [104] Typical weather forecasts can be received at sea through the use of RTTY, Navtex and Radiofax.
A weather forecasting technique in which a numerical weather model generates a set of multiple (often several dozen) forecasts, each based on a slightly different set of initial atmospheric conditions, intended to provide an indication of the range of possible future states of the atmosphere. If the forecasts are consistent, they are usually ...
A Short-Term Forecast NOW (alt., NOWcast) is an event-driven narrative outlook of near-term weather conditions within the Weather Forecast Office’s area of responsibility, typically valid for a three- to seven-hour period. The product outlines any ongoing or recently occurring conditions—based on radar analysis, satellite imagery and other ...
The first daily weather forecasts made by FitzRoy's Office were published in The Times newspaper in 1860. The following year a system was introduced of hoisting storm warning cones at principal ports when a gale was expected. FitzRoy coined the term "weather forecast" and tried to separate scientific approaches from prophetic ones. [73]
Weather is the state of the atmosphere, describing for example the degree to which it is hot or cold, wet or dry, calm or stormy, clear or cloudy. [1] On Earth, most weather phenomena occur in the lowest layer of the planet's atmosphere, the troposphere, [2] [3] just below the stratosphere.
The first Weather Bureau radiosonde was launched in Massachusetts in 1937, which prompted a switch from routine aircraft observation to radiosondes within two years. The Bureau prohibited the word "tornado" from being used in any of its weather products out of concern for inciting panic (a move contradicted in its intentions by the high death tolls in past tornado outbreaks due to the lack of ...
A weather presenter (also known as a weather girl, weatherman or weather broadcaster) is a person who presents the weather forecast daily on radio, television or internet news broadcasts. Using tools such as projected weather maps , they inform the viewers of the current and future weather conditions, explain underlying reasons, and relay ...
