Image Narration | Intertropical Convergence Zone
HIPPO Principal Investigator Steve Wofsy, narrates this image of the Intertropical Convergence Zone as it is seen from the this picture when the NSF/NCAR GV was approaching the equator.
This photograph was taken from the aircraft as it was approaching the equator. What you seen there is the Intertropical Convergence Zone, where the two hemispheres meet. The southern hemisphere is beyond it, the northern hemisphere is where we’re coming from.
Right along the Intertropical Convergence Zone you see a series of thunderstorms which are basically going twenty-four hours a day and mark the place where the air from the hemispheres meet and ascend up into the middle troposphere, a very important part of the atmosphere. It’s very interesting part to look at to see how the dynamics is actually moving trace gases and water vapor and all of the things that we are interested in from the near surface environment in the tropics into the middle troposphere.
