  • The International Business Machines Corporation, known as IBM, says it is making technology for precision weather predictions available to everyone.
  • 2
  • The company said the new weather forecasts offer more details and bring a level of precision once available only in major industrial countries.
  • 3
  • The forecasting tool is expected to help emergency officials better predict where severe storms will hit.
  • 4
  • It may also aid airline companies planning flight paths, as well as farmers caring for crops.
  • 5
  • The new system creates weather forecasts more often and with finer details than what is available outside the United States, Europe and Japan.
  • 6
  • Most forecasts have a resolution of 10 to 15 square kilometers and provide new information every six to 12 hours.
  • 7
  • IBM's Global High-Resolution Atmospheric Forecasting System goes down to 3 square kilometers and provides information every hour.
  • 8
  • "That's providing a level of detail that we've not been able to see in parts of the world such as Southeast Asia, Africa as well as South America," notes Kevin Petty.
  • 9
  • He serves as director of science and forecasting at The Weather Company, which IBM owns.
  • 10
  • That kind of precision can provide details of where and when extremely heavy rain will fall.
  • 11
  • That could be useful in emergency situations, and could help farmers decide when to plant, harvest and fertilize crops.
  • 12
  • Fred Carr is emeritus meteorology professor at the University of Oklahoma, and was not involved with the project.
  • 13
  • Carr says the United States has a similar high-resolution forecasting system, "but it's just for the U.S. because it takes so much computer time. To do it for the whole globe is a pretty significant achievement."
  • 14
  • Carr added that it is possible to quickly collect observations from radar, airplanes and surface measurements in the United States.
  • 15
  • But he said it is not clear how IBM gets information from the other 98% of the world.
  • 16
  • Carr said he believes there will be problems in getting information, so "sometimes those forecasts aren't going to be very accurate."
  • 17
  • Users will be able to decide for themselves.
  • 18
  • The system now operates on the Weather.com website and The Weather Channel's application program for smartphones.
  • 19
  • In the future, IBM hopes to improve its forecasts by collecting information from atmospheric pressure sensors used in such phones.
  • 20
  • These sensors improve the precision of global positioning system, or GPS, technology.
  • 21
  • For example, they can help fitness tracking instruments measure how many steps a user has climbed.
  • 22
  • IBM said it is not currently using this information but plans to offer users the chance to choose it.
  • 23
  • Some privacy activists and governments have criticized technology companies for collecting this kind of information.
  • 24
  • The city of Los Angeles, California has brought a case against IBM for improperly using location information from Weather Channel app users.

  • I'm Jonathan Evans.
