A better look at the arrow symbols used in the illustration.
A closer view of the cloud formations, derived from satellite data, used in the model.
This diagram illustrates, in a generalised fashion, the location and movement of this particular meteorological phenomenon. The jet streams are a series of changeable, typically undulating, currents of strong westerly winds that occur high in the atmosphere. They affect global weather patterns by impacting upon air pressures and temperatures closer to the surface of the Earth.
One of the main challenges when producing this model was to combine as seamlessly as possible 'real' data, captured by satellite, with computer generated graphics. In order to achieve this it was felt necessary to adjust the colours of the satellite image. It was perceived that a more 'natural', less saturated, looking image would not have sat so comfortably against the 'gel' like arrow features.
Data from the following source was used in the compilation of these illustrations: Blue Marble: Next Generation: NASA's Earth Observatory.
