Astronomy Picture of the Day

   [1]Discover the cosmos! Each day a different image or photograph of our
      fascinating universe is featured, along with a brief explanation
                    written by a professional astronomer.

    [2]The picture shows a the paths of tropical storms across Earth from
   1985 to 2005. Please see the explanation for more detailed information.

   Explanation: Where on Earth do cyclones go? Known as [8]hurricanes when
   in the Atlantic Ocean and typhoons when in the Pacific, the [9]featured
   map shows the path of all major storms from 1985 through 2005. The map
   shows graphically that [10]cyclones usually occur over water, which
   makes sense since evaporating warm water [11]gives them energy. The map
   also shows that [12]cyclones never cross -- and rarely approach -- the
   [13]Earth's equator, since the [14]Coriolis effect goes to zero there,
   and cyclones need the Coriolis force to circulate. The [15]Coriolis
   force also causes [16]cyclone paths to arc away from the equator.
   Although long-term trends remain a [17]topic of research, evidence
   indicates that [18]hurricanes have become, on the average, [19]more
   powerful in the North Atlantic over the past 30 years, and their power
   is [20]projected to keep increasing.
