Weather Facts
Formation of hurricanes in the North Pacific Ocean occurs in two basins. They are the two most active basins for tropical cyclones on our planet. Meteorologist recognized the north eastern Pacific Ocean basin in the 1920s.
One-third of all tropical storms form in the western Pacific Ocean basin that includes all the Pacific Ocean above the equator and west of the International Date Line.
What causes lightning to suddenly strike out of the blue without warning? You are 9 times more likely to die by lightning that a venomous snake bite. Every year 80 people struck by lightning die.

The Earth’s atmosphere has layers just like the interior of the Earth. The four major layers of atmosphere that are separated by temperature. The tropopause, stratopause, mesopause and are areas where two atmosphere layers gradually transition from one layer into another layer.
What is air pressure? It is the weight of air molecules pressing down on the Earth. The pressure changes as you move upward into the atmosphere. The greatest density of air is at sea level. As you move upward into the atmosphere the gravity keeping air molecules from floating away decreases until molecules are so far apart they rarely collide.
Thunderstorm clouds form when warm air currents rise above the Earth’s surface creating cumulonimbus clouds. These clouds produce rain, lightning, hail and occasionally tornadoes.
