MID-LATITUDE CYCLONES

Mid-latitude cyclones are organized low pressure systems that have cold and warm fronts. The development of mid-latitude cyclones is part of the process known as cyclogenesis. Expand the MID-LATITUDE CYCLONES folder. Click Migration. This animation shows the development and migration of a mid-latitude cyclone, as well as satellite imagery (Note: The satellite imagery section might take a few minutes to upload). Now, you will go through the cyclogenesis of a mid-latitude cyclone on Google Earth. Return to Google Earth. Double-click and select Day 1 This map shows a typical initial development of a mid-latitude cyclone. The center of the system has the lowest pressure, which is located along the jet stream (blue arrows). The system travels in an easterly direction along the jet stream, with the warm front leading, followed by the cold front. The stage of cyclogenesis is the open stage. Uncheck Day 1. Select Day 2. The system continues moving eastward along the jet stream. The cold front is traveling faster than the warm front and the distance between the two fronts is decreasing. With the distance between the fronts becoming smaller, cooler air starts to push the warmer air, and the warmer air begins to move upwards. The stage of cyclogenesis is the mature stage. Uncheck Day 2. Select Day 3. Now, the cold front has caught up with the warm front and forms an occluded front. The warmer air is now aloft (above the surface) and precipitation may occur. This stage of cyclogenesis is the occluded stage.
