"Big Data" is expected to predict 40 days of weather

The weather is difficult to predict and control. But now one company is trying to use big data to predict the weather.

Earthrisk is a technology company that uses big data to forecast future http://www.aliyun.com/zixun/aggregation/18332.html "> Weather forecasts." Earthrisk's flagship product is Temprisk. It uses a predictive model from the University of California's Institute of Oceanography, this model is different from the previous numerical prediction model, can be based on 82 billion calculations and 60 meteorological history data to identify the weather patterns, and then compare these models with the current climate conditions, and then use predictive analysis of weather forecasts, The prediction time is longer, the prediction is higher, the maximum can be 40 days ahead of the hot and cold weather probability, and the traditional model of subjective prediction of more than a week's quasi degree is not.

The thousands of variables that affect the weather all the time are constantly changing, and the traditional model has no way to take all the factors into account. Therefore, the traditional model always needs some basic assumptions, once the initial conditions of these assumptions are wrong, then the entire analysis of the prediction will be too far. Earthrisk, however, uses statistical relationships to predict the final results, which are not subject to the above restrictions.

Earthrisk's data come from observational data from the US and British governments and thousands of meteorological researchers, as well as databases updated daily. The engine searches for correlations and patterns of statistical significance, and then generates forecast probabilities on this basis. To predict the future through the past.

Temprisk is the first commercial application of the technology. For utilities, energy trading and production industries that are affected by weather changes, the prediction of time and degree of alignment will play a big role in business decision making. Earthrisk has been developing, refining and testing the technology for several years and is now planning a major commercial expansion. Consumer-oriented applications are also being developed, and future consumers may be able to use their applications to check the weather when they plan to travel to typhoon zones.
