3. Telegraph and Weather Bureaus: The telegraph allowed for the rapid transmission of weather data over long distances, leading to the establishment of national weather bureaus in the 19th century.
4. Computational Models: In the mid-20th century, the development of computers enabled the use of mathematical models to simulate the atmosphere, significantly improving forecast accuracy.
5. Satellites and Radar: The launch of weather satellites in the 1960s and the development of weather radar systems revolutionized the collection of meteorological data.

Modern Weather Forecast Technology:

Today, weather forecasting relies on an array of advanced tools and technologies that gather data from various sources, process it through complex computer models, and provide forecasts for various time frames.

1. Data Collection:

• Weather Satellites: Orbiting Earth, weather satellites capture images and data on cloud cover, temperature, humidity, and other atmospheric conditions. Geostationary satellites provide real-time data, while polar-orbiting satellites offer a global view of the atmosphere. READ MORE:- avoidmake-up4
• Radar Systems: Doppler radar systems use radio waves to detect precipitation, its intensity, and movement. This data is essential for short-term forecasts and severe weather warnings.
• Weather Stations: Ground-based weather stations, equipped with instruments like anemometers (for wind speed), barometers (for pressure), and thermometers, provide local weather data.
• Weather Balloons: Radiosondes attached to weather balloons are launched into the atmosphere to collect temperature, humidity, and pressure data at different altitudes.
