xkcd #3107: Weather Balloons

Title text:

Once you add the balloons into the model, it makes forecasting easier overall--the forecast is always 'cold and dark, with minimal solar-driven convection.'

Transcript:

[A graph is shown. The X axis is labeled Number of Weather Balloon Launches Per Day. It's logarithmic, with ticks in powers of 10, and values shown at 1, 10, 100, 1,000, 1 million, 1 billion, and 1 trillion. The Y axis is labeled Weather Model Accuracy, no values are shown. The plot starts above the mark for 1 balloon, at about 40% of the maximum value of the curve, it quickly rises through a point labelled "Current Rate", at about 4000 launches per day and 85% of the maximum. The maximum value is reached at 100 million, plateaus until 10 billion, and then reduces even more rapidly down to perhaps 15% maximum accuracy above the 10 trillion mark.]
