更好的天气预报即将来到发展中国家

The International Business Machines Corporation,known as IBM,says it is making technology for precision weather predictions available to everyone.

国际商业机器公司(IBM)表示,它正在向所有人提供精确的天气预报技术。

The company said the new weather forecasts offer more details and bring a level of precision once available only in major industrial countries.

该公司表示,新的天气预报提供了更多的细节,并带来了一度只有主要工业国家才能获得的精度水平。

The forecasting tool is expected to help emergency officials better predict where severe storms will hit.It may also aid airline companies planning flight paths,as well as farmers caring for crops.

预计这一预测工具将帮助应急官员更好地预测严重风暴将袭击的地点。它还可能帮助航空公司规划飞行路线,以及农民照顾庄稼。

The new system creates weather forecasts more often and with finer details than what is available outside the United States,Europe and Japan.

与美国、欧洲和日本以外的国家相比,新系统更经常地创建天气预报,并提供更精细的细节。

Most forecasts have a resolution of 10 to 15 square kilometers and provide new information every six to 12 hours.IBM's Global High-Resolution Atmospheric Forecasting System goes down to 3 square kilometers and provides information every hour.

大多数预报的分辨率为10至15平方公里,每6至12小时提供一次新的信息。IBM的全球高分辨率大气预报系统可以达到3平方公里,每小时提供一次信息。

"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.He serves as director of science and forecasting at The Weather Company,which IBM owns.<纽约时报中英文网 http://www.qqenglish.com/>

凯文•佩蒂指出:“这提供了一个我们在东南亚、非洲以及南美等地所无法看到的细节水平。”。他在IBM旗下的气象公司担任科学和预报主任。

That kind of precision can provide details of where and when extremely heavy rain will fall.That could be useful in emergency situations,and could help farmers decide when to plant,harvest and fertilize crops.

这种精确性可以提供特大暴雨发生的地点和时间的细节。这可能在紧急情况下有用,并有助于农民决定何时种植、收获和施肥。

Fred Carr is emeritus meteorology professor at the University of Oklahoma,and was not involved with the project.

弗雷德·卡尔是俄克拉荷马大学气象学名誉教授,他没有参与这个项目。

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."

卡尔说,美国也有类似的高分辨率预测系统,“但这只是针对美国的,因为它需要太多的计算机时间。为全世界做这件事是一项相当重大的成就。”

Carr added that it is possible to quickly collect observations from radar,airplanes and surface measurements in the United States.But he said it is not clear how IBM gets information from the other 98%of the world.

卡尔补充说,有可能从美国的雷达、飞机和地面测量中快速收集观测数据。但他表示,目前尚不清楚IBM如何从全球98%的地区获取信息。

Carr said he believes there will be problems in getting information,so"sometimes those forecasts aren't going to be very accurate."

卡尔说,他相信在获取信息方面会有问题,所以“有时候这些预测不会非常准确”

Users will be able to decide for themselves.The system now operates on the Weather.com website and The Weather Channel's application program for smartphones.

用户可以自行决定。该系统现在在Weather.com网站和Weather频道的智能手机应用程序上运行。

In the future,IBM hopes to improve its forecasts by collecting information from atmospheric pressure sensors used in such phones.

在未来,IBM希望通过从这些手机中使用的大气压力传感器收集信息来提高预测。

These sensors improve the precision of global positioning system,or GPS,technology.For example,they can help fitness tracking instruments measure how many steps a user has climbed.

这些传感器提高了全球定位系统(GPS)技术的精度。例如,它们可以帮助健身跟踪仪器测量用户爬了多少步。

IBM said it is not currently using this information but plans to offer users the chance to choose it.

IBM表示,它目前并不使用这些信息,但计划为用户提供选择这些信息的机会。

Some privacy activists and governments have criticized technology companies for collecting this kind of information.The city of Los Angeles,California has brought a case against IBM for improperly using location information from Weather Channel app users.

一些隐私活动家和政府批评科技公司收集此类信息。美国加利福尼亚州洛杉矶市对IBM提起诉讼,指控IBM不当使用气象频道应用程序用户提供的位置信息。
