Weather prediction is concerned with the forecasting of atmosphere on the earth at a given time and place. Weather can be cold, warm, wet, dry and humid. Weather conditions depend on the condition of air and subsequently, the influence caused due to heat and water on the climatic conditions. Weather predictions involve the application of scientific technology to forecast the atmosphere of a particular location. Also, human beings had attempted to forecast the weather, by the observations seen in the atmosphere. Predictions of weather at present comprises of collecting numerical data, with respect to the current atmosphere and using scientific technologies to predict the future climatic conditions. Meteorological departments located in each area predict the weather depending on the atmosphere.
How to Predict Weather?
Weather Predictions are done by Meteorologist, who can be called as scientists monitoring the weather situations. Through the sampling of several networks of weather stations and satellites, meteorologists plot the positions of huge masses of air that are circling the Earth. Air masses have a tendency to interact relatively in a usual way and hence, meteorologist can simply forecast the patterns observed in weather with utmost accuracy. Since, weather is seen to be affecting several aspects of life, meteorological advancements are increasingly gaining importance. Prediction of weather requires use of several instruments such as thermometers for measuring heat, barometers for measuring pressure in the air, anemometers for measuring the wind speed, hygrometers for measuring the humidity in air, wind vanes for measuring the direction of wind, rockets, radars and satellites. The process of predicting weather becomes simple, once the data is received forms the numerous stations across the country. The assimilated data is fed in the computer and the software’s itself develops maps.
Understanding the Weather Forecast Maps:
The maps which an individual usually comes across while studying the weather predictions are complex. They have numerous isobar lines, which demarcates the areas of high pressure from that of low pressure. Weather Fronts classified as cold, warm and stationary fronts reflects the different air masses in the atmosphere. The varied air-masses while predicting weather could be high and dry, low and dry, high and wet, low and wet air masses. While predicting weather precipitation areas as well as cloud covered areas are also indicated in the map.
