1960年,美国麻省理工学院教授洛伦兹研究“长期天气预报”问题时,在计算机上用一组简化模型模拟天气的演变。他原本的意图是利用计算机的高速运算来提高长期天气预报的准确性。但是,事与愿违,多次计算表明,初始条件的极微小差异,均会导致计算结果的很大不同。 In 1960, MIT professor Lorentz studied the problem of “long-term weather forecast”, and used a simplified model to simulate the evolution of the weather on a computer. His original intention was to use computer high-speed calculations to improve the accuracy of long-term weather forecasts. However, contrary to expectations, many calculations have shown that very small differences in initial conditions can lead to large differences in calculation results.
