let's talk with lloyd treinish. he's an ibm scientist & global expert on weather prediction. lloyd, give us the thumbnail explanation for this. > > well, precision agriculture or precision farming is about having better information for farmers to schedule their various operations. weather is a key component of that. the idea is that we connect precise weather forecasts to those farming operations. > > that's the theory, but has it been proven? is it an actual data-crunching system that's being used here? > > well, it's a combination of advanced computing technology from ibm and advanced software, but also sophisticated mathematics and the science behind meteorology. we used data from many sources - data coming from the national weather service, data coming from farms - to predict not just the weather, but how that weather impacts farms. > > lloyd, tell me, what exactly does this do? what does this information do for, say, the farmer? > > well, instead of getting a generic and fairly vague weather forecast, we can provide a detailed forecast of when and where it might rain tomo
