How Much Does a Cloud Weigh ?

1.1 million pounds

Cloud weights 1.1 million pounds

How to measure the weight of a cloud

  • How dense the cloud is = 1/2 gram per cubic meter
  • How big the cloud is = a kilometer long and a kilometer tall.
  • Do the math with the density and volume to determine the total water content of the cloud. In this case, it’s 500,000,000 grams of water, or 1.1 million pounds. Volume= Mass / Density
  • How does a several-hundred-ton cloud stay afloat ? It’s distributed among trillions of tiny water droplets spread out over a really big space. Some of these droplets are so small that you would need a million of them to make one raindrop, and gravity’s effect on them is pretty negligible.

Where is the Hottest Place on Earth ?

El Azizia, Libya

  • Libya is the hottest country in the world with extreme hot temperature throughout the year. Libya is a country with a small population which is located in the Northern Africa. The highest temperature ever recorded was in Libya of 136.04°F (57.8°C). Most part of country consists of Libyan Desert which is dry and hot.
  • Satellites can get a reading on these hard-to-reach, harsh places because they can scan every piece of the Earth’s surface. The satellites take what is called “land skin temperature,” which tells the amount of heating of a certain parcel of ground from the sun, the atmosphere and other heat sources.

Fujita Scale

  • The Fujita scale (F-Scale), or Fujita–Pearson scale, is a scale for rating tornado intensity, based primarily on the damage tornadoes inflict on human-built structures and vegetation.
  • The original Fujita scale was developed  by a prominent Japanese-American Dr. T. Theodore Fujita (1920-1998) and was put into use in 1971.
  • His research at the University of Chicago on severe thunderstorms, tornadoes, hurricanes and typhoons revolutionized knowledge of each.
  • The scale was enhanced in 2007, with rankings running from Enhanced Fujita – 0 through 5. The ratings are based on the amount and type of wind damage.

What are Clouds made of ?

Ice Crystals 

Clouds form when the invisible water vapor in the air condenses into visible water droplets or ice crystals. There is water around us all the time in the form of tiny gas particles, also known as water vapor. There are also tiny particles floating around in the air – such as salt and dust – these are called aerosols.
