An anonymous reader writes: The Times reports that IBM has agreed to acquire the Weather Company's data and digital properties including Weather.com and Weather Underground news sites. The deal does not include the Weather Channel. Techcrunch reports: "According to IBM, the acquisition helps it to harness one of the largest big data opportunities in the world: weather. That's something that impacts one-third of the world's GGP and in the U.S. alone, accounts for about half a trillion dollars in impact, the company notes. The deal will combine two big data platforms, IBM's cognitive and analytics business with that of Weather. Currently, The Weather Company has the fourth-most visited mobile app in the U.S. and handles 26 billion inquiries to its cloud-based services daily, generating about 4 GB of data per second. Following the acquisition, IBM's Watson will be able to tap into more data sets, including Weather's mobile and web properties, which analyze data from 3 billion weather forecast reference points, over 40 million mobile phones, and 50,000 flights per day."
