Evolution of technology on weather forecast?

For the simple reason that weather systems are enormously complicated. And it is not possible to take all the measurements needed to make foolproof predictions. Vast areas of the ocean have no weather buoys to beam data via satellite to ground stations. Rarely do weather-model grid points correspond exactly to the location of weather observatories. Besides, scientists still do not understand all the forces of nature that shape our weather.
In recent years man has been trying to take the unpredictableness out of the weather. The weather follows laws, but these laws are complicated. Early in this century, British meteorologist Lewis Fry Richardson tried to use mathematical formulas based on the laws of heat and motion to predict the weather. His equations were so long, however, that usually the weather arrived before he finished his calculations. Scientists today use computers. With satellites, balloons, rockets, and so forth, they watch the atmosphere closely, feed information about it into computers, and thus try to foretell the weather. Their short-term forecasts are often quite successful, but the mechanisms for long-term weather patterns still elude them.
