Bone drilling worms, severe weather from space and beautiful cherry blossoms made our top picks for this months. See what the Earth brought us this month.
Tornadoes are the most powerful, unpredictable and destructive weather systems on Earth. The National Weather Service (NWS) defines a Tornado as a violently rotating column of air in contact with the earth’s surface (land or water) and commonly associated with a severe thunderstorm.A tornado generally occurs when high winds within a low pressure system (such as a thunderstorm) cause water vapor in the air to condense in to a condensation funnel cloud. Many less severe tornadoes are not even visible to the human eye. Major tornadoes usually become more visible when the strong winds within the funnel lift up dirt and debris off the Earth’s surface. Tornadoes are generally classified as either a land spout (a tornado on land), a water spout (a tornado that forms over water) or a gustnado (a small tornado caused by a strong downburst of wind from a thunderstorm).The average tornado has maximum wind speeds of about 112 mph or less, measures around 250 feet in width and travels approximately one mile before falling apart. Some of the most catastrophic tornadoes in recorded history have had winds in excess of 300 miles an hour (twice that of a category 5 hurricane), have measured more than 2 miles in girth, and have carved devastating paths of destruction miles and miles in length.
April 25-28, 2011, marks one of the deadliest tornado super outbreaks in recent history, with a total of 358 confirmed tornadoes.
The direct experience of a devastating natural disaster does little to make people more realistic about their own vulnerability to future threats compared with others.
Mother Earth gave us a lot to look at this month waterspouts in Tampa, record snowfall from space and even antlers without a reindeer. Don't miss these amazing photos.
Rare sharks, big meteorites, volcanic eruptions from space and hidden canyons under the sea are just a few of the images we discovered this week. Click on to check them all out.
From snow to flooding, temperatures extremes, damaging winds and deadly tornadoes, this storm system had it all. This story recaps the dramatic events of the midweek storm.
