Water Vapor Tutorial
Let’s use today’s (11/14/11) Water Vapor Sat Photo as a tutorial example of what the colors stand for, this is an image of the Pacific Ocean and west USA coastline. The area West of central California down to just below the tip of Baja California and out to the 135th Longitude is colored dull orange with black surrounding dull orange, this denotes a lack of Water Vapor. A similar area is seen surrounding Hawaii. The White color equals very little water vapor, The light Green changing to darker green equals increasing water vapor. Just below the 10th Latitude between the 150th and 120th longitude we see these green colors have bright Orange and Magenta areas inside of them, these are wetter areas of higher water vapor. Note that “contrails” need water vapor to form. In the second Sat photo (the black and white one) we see large white lines forming in the area off California where there is little to no water vapor.
