We really don't think consciously about it, weather impacts every aspect of our life. It impacts our mood, what we wear, where and when we shop, what we eat, when we sleep -- the list is endless ...
So why don't we use weather more in our analytics and insights services to determine the real relationships and how to impact sales, ads, etc ... through the just announced availability of a range of weather APIs in IBM's Bluemix, anyone can now develop apps and services that integrate weather. This is just the start of a continued availability of services and solutions that integrate weather -- predictive, current, and historical - into our solutions.
