Ben Kyger says oceans are another issue because they closely interact with the atmosphere and have a huge effect on storms. NOAA has spent about $20 million on two new supercomputers, in an effort to improve the dependability of its forecasts.
It takes a huge amount of computational power to examine data from weather satellites, ground stations and other sources. It then takes a lot of power to predict temperature, air pressure, humidity and wind speed.
But human brains and experience are still very important to the process. Meteorologists at the National Centers for Environmental Prediction scan the same data that the supercomputers get before issuing a weather report.
NOAA issues worldwide forecasts every six hours every day of the year. The reports are free and are helpful for many countries that cannot afford their own weather service. NOAA continues working to improve its weather-forecasting abilities. Another upgrade of its weather-predicting supercomputers is planned for as early as 2015.本·基格说海洋是另一个因素，因为海洋与大气密切互动，对风暴有巨大的影响。美国国家海洋和大气管理局在两台新型的超级计算机上耗资2000万美元，希望能提高预测的可靠性。
分析来自气象卫星、地面站及其他来源的数据，并预测气温、气压、湿度和风速（等一系列过程）都需要巨大的计算能力。
不过人脑（智慧）和经验对该过程来说仍至关重要。国家环境预报中心的气象学家们会在审查超级计算机获取的数据后才发布天气预报。
美国国家海洋和大气管理局每隔6小时发布一次世界各地的天气预报，全年周而复始昼夜不断。这些免费的预报为许多无法自行承担天气服务的国家提供了便利。美国国家海洋和大气管理局将继续增进其预测天气的能力。按计划，下一次对天气预报超级计算机的升级将在2015年进行。
