Patterns, Similarities, and Differences: Seasonal Ice (2012)
Explore the spatial patterns observed in meteorological data and learn how this information is used to predict weather and understand climate behavior. By observing patterns in data we can classify our observations and investigate underlying cause and effect relationships.
Seen side-by-side, snow and sea ice in the Northern and Southern Hemispheres pulse at exact opposite times of year, constantly out of phase. The extent of yearly change at the extreme poles of our planet is an annual pattern that illustrates that similar forces are at work on distant parts of the Earth. Moderate Resolution Imaging Spectroradiometer (MODIS) data from the near-polar-orbiting Terra and Aqua satellites were used for this visualization.
