一个new global weather systemis set to improve local forecasts around the globe, created by IBM and its subsidiary The Weather Company.
该系统在CES 2019上宣布，被称为IBM全球高分辨率大气预测系统（GRAF），“将是第一个每小时更新的商业天气系统，能够预测全球雷暴与雷暴一样小”，”according to IBM。传统系统的更新窗口为6到12个小时。
IBM估计，与许多世界范围内使用的现有预测模型相比，GRAF将为全球大部分地区的预测分辨率提高200％（从12 km到3平方公里），这些预测模型涵盖了12至15公里的土地。

沃森媒体和IBM天气总经理卡梅隆·克莱顿（Cameron Clayton）说：“如今，世界各地的天气预报并不是平等的，所以我们正在改变这一点。”“天气影响人们日常工作，可以说是业务绩效中最重要的外部摆动因素。随着极端天气变得越来越普遍，我们的新天气系统将确保世界各地的每个人和组织都能获得更准确，更精细的天气预报。”
The system bypasses the lack of equipment from many regions by utilizing aircraft sensor data. This technique can also give people a chance to improve local weather forecasts themselves, since “it will be able to make use of pressure sensor readings sent from barometers found within smartphones if people opt-in to sharing that information,” according to IBM.
GRAF将其数据分析将基于IBM Power9的超级计算机提供给。
The system will be available globally sometime in 2019.
