Weather Visualization Aids: Satellite Imagery and Weather Charts/Maps

Visible Satellite Image -- 1500 UTC 3 September 2002
UTC = Coordinated Universal Time = Greenwich Mean Time = PDT (GMT - 700)

How can you tell that clouds at different levels are shown?
The cloudiness outlining the coast is fog. It is known to meteorologists as "stratus."


This is a visible satellite image from the US Navy.The yellow lines are elevation contours in meters.
"Z" stands for military time. Same as GMT.

What is the date and time stamp for this image?
Characterize the image...do you see a pattern?


An even closer view of our area from the US Navy.

Describe the pattern? Why do the clouds appear to be outlining the coast? Date and time?


Another way of visualizing the weather...is by examining actual weather observations.

Date and time?


A schematic chart with conceptual wind arrows. The longer the arrow, the stronger the wind...also color coded so that the greens and yellows are the strongest winds. Where are the winds the strongest?


A chart showing the distribution of temperatures from the ground to 1500 meters at Fort Ord (Monterey) at different times. How does this chart "jive" with what you would expect from the patterns shown on the previous chart?


A chart showing the distribution of temperatures from the ground to 1500 meters at Sacramento at different times. Does this chart and the last illustrate something very prominent about the low elevation summer climate of California?
