Weather satellites have particular equipments that after scanning the earths surface form images. Interpretation of visible infrared images from satellites can be the beginnings of derecho detection. The infrared images that are recorded by scanning radiometer sensors allow trained forecaster to verify cloud type and height. Tropical cyclones utilize satellite imagery caused by infrared lasers. Infrared lasers are not affected by light or darkness (Norris, 67). Derechos are determined by the cloud alignment, the patterns and progression of successive images.
Google maps enable the analyst to identify derechos in that they give a specific location of the storm. Google looks to the earth from orbiting satellites, where general perspective projection enables this effect to be achieved. Googles LatLong blogs announce all imagery updates to detect derechos.
