Unsealed: Alien Files – Atmospheric Anomalies episode 46: Some believe that extraterrestrials cause atmospheric light shows and question whether they pose an imminent threat to humanity.
In April 2011 the FBI declassified decades’ worth of secret government documents that contain thousands of reports of UFO sightings and alien activity. Each episode of this half-hour series tackles one alien case by investigating the previously off-limits government files. The program re-examines key evidence and follows developing leads based on newly released information.
Mass UFO sightings, personal abductions, government cover-ups, and alien news from around the world are some of the topics covered by the show’s panel of specialists, who include journalists, researchers, and radio and TV hosts. After watching an episode of `Unsealed: Alien Files’, you may begin to believe that `we are not alone’.

Anomaly (natural sciences)
In the natural sciences, especially in atmospheric and Earth sciences involving applied statistics, an anomaly is a persisting deviation in a quantity from its expected value, e.g., the systematic difference between a measurement and a trend or a model prediction. Similarly, a standardized anomaly equals an anomaly divided by a standard deviation. A group of anomalies can be analyzed spatially, as a map, or temporally, as a time series. It should not be confused for an isolated outlier. There are examples in atmospheric sciences and in geophysics.
In the atmospheric sciences, the climatological annual cycle is often used as the expected value. Famous atmospheric anomalies are for instance the Southern Oscillation index (SOI) and the North Atlantic oscillation index. SOI is the atmospheric component of El Niño, while NAO plays an important role for European weather by modification of the exit of the Atlantic storm track. A climate normal can also be used to deriva a climate anomaly.
