Water Vapour
Meteosat I, launched in 1977, was the first geostationary satellite with a water vapour band. The water vapour images are used to analyse the middle tropospheric stream between 300 and 600 hPa. The images reveal the direction and the speed of invisible air masses. Meteorologists observe the general weather situation as well as the development of thunderstorms.
The circular flow is clearly seen in the animation.
Open the LEOWorks programme. If you have not downloaded the weather images yet, do so now.
| | Selection of the images for the animation | |
Select Tools>Image Animation and choose the images. With a click on Open the window, Image Animation appears on the screen and shows an excessively fast animation. Shift the slide Frames/Sec to about 2.9 frames per second, and the sequence will slow down.
Describe the circular flow at the northern and southern hemispheres and at the equator.
Compare the direction of circular flow on 30 June 2002 with those on other days. For that purpose, create 3 new animations using the data for 31 March 2002, 30 September 2002, and 31 December 2002.
What analogies can be drawn?
