Latitude plays an important role in governing Martian weather.  Mars' axis of rotation is tilted 25.19 degrees from perpendicular.  As a result, Mars has a wider tropic belt than is seen on Earth.  The Martian arctic circle would also be larger thus encompassing a lower latitude.  The end result:  Mars is a planet of extremes.
     Mars does not have a very large temperate zone.  On Earth, if one lives between 66.5 N and 23.5 N latitude, the widest possible range of weather would be experienced by an observer there.  The observer might see thunderstorms in the spring and summer shortly followed by persistent high pressure which yields unchanging warm weather followed by yet another wave of cyclonic activity.  In the fall, the weather could be quite warm one day but uncomfortably cold the next day.  Winter time could bring large snowstorms one day and the next day there could be warmer, snow melting temperatures.  On Mars, since the temperate zone is a narrow belt sandwiched between the tropics and the arctic circle, the extremes would be even more extreme.  The major difference would be that since Mars makes a trip around the sun in 687 Earth days, the extreme swings in weather may occur less quickly on Mars.  This very narrow belt (39.62 degrees compared to Earth's 43 degrees) which comprises Mars' temperate zone is the site of Mars' most interesting weather phenomenon:  the globe encompassing dust storms.  These large dust storms are a testimony to the extreme environment of Mars.
