    The Coriolis effect is an "apparent" effect, an illusion produced by a rotating frame of reference. This type of effect is also known as a fictitious force or an inertial force. The Coriolis effect occurs when an object moving along a straight path is viewed from a non-fixed frame of ://   reason for the relationship. b. the average rainfall or temperature for the whole period of record does not change. c. the mean for the 30 yr period ending in the last year of the last decade (currently ) reflects the long term mean. d. the occurrence of one event is linked, by statistical test to the occurrence of another event.

Most major snowstorms are closely associated with strong troughs of the main jet stream approaching the boundaries of sharply contrasting air masses and the resulting major surface cyclones.

Barely a week goes by these days in the Northern Hemisphere without the jet stream being mentioned in the news, but rarely do such news items explain in detail what it is and why it is important.
