For Gavin Pretor-Pinney, hell might be someplace like Yuma, Arizona, said to be the sunniest city on Earth and boasting more than 4,000 blinding hours of sunshine a year.
As an ardent amateur cloudspotter and the founder of the Cloud Appreciation Society, the UK-based Pretor-Pinney spends much of his time gazing at clouds, those suspended particles of liquid water and/or ice that are, he says, an intrinsic part of our existence on Earth. “Clouds are the ever-present backdrop to human culture,” he says, affecting the weather, climate and creative imagination. In March 2017, Pretor-Pinney played a role in expanding the vocabulary of clouds when asperitas, a formation that he was the first to bring to public attention, was included in the most recent edition of the International Cloud Atlas, the official list maintained by the World Meteorological Organization (WMO). Eleven other formations were also added.

Atmospheric Pressure Makes The Wind Blow. Atmospheric Pressure - What Makes The Wind Blow?
Many of the forces within our atmosphere are easily recognized by us. This is due to the fact that we can use our senses to feel these forces. We can, for example, quickly determine the approximate temperature outside simply by stepping outside. We immediately know whether it is cold, warm or hot. Likewise, we can feel the amount of wind, or see the level of windiness by looking at how forcefully the trees are swaying back and forth. Stuff to Blow Your Kid's Mind: Atmospheric Pressure.

The more water that is in the air there is, the higher we say that the humidity has risen. Humidity can be measured in a number of ways. These include absolute humidity, specific humidity, and relative humidity. Absolute and specific humidity measure the exact physical amount of water in the air, while relative humidity compares how much water is in the air with how much could be in the air, or in other words, with the maximum vapor pressure. Suppose that given the local temperature and wind, the maximum vapor pressure allows a certain volume of air to hold 100 pounds of water.

Introduction To Our Atmosphere - Part II. Introduction To Our Atmosphere - Part II By watching these particulates, we can get an idea of just how volatile the atmosphere is.
What would happen, in our previous experiment, if we blow into the light? Doing so would reveal how quickly the air around us gets mixed up. Imagine what happens outside as storms blow the Earth’s atmosphere this way and that. Imagine how quickly the gases in our atmosphere are mixed together. The Earth’s atmosphere extends outward to a distance of approximately 6,000 miles. The varying pressures of our atmosphere at different elevations has important effects on the weather, on animals and people, and on man-made devices. Layers of The Atmosphere. The Layers of Our Atmosphere In order to better understand our atmosphere, scientists have divided it into several layers.
These layers are divided based on the characteristics of the gases found at that height. Imagine a layered cake. A layered cake is made out of layers of different ingredients. The first layer might be cake mix. Science for Kids: Earth's Atmosphere. Science >> Earth Science for Kids The earth is surrounded by a layer of gases called the atmosphere.
The atmosphere is very important to life on Earth and does many things to help protect life and help life to survive. A Big Blanket. What is the greenhouse effect? Air Pressure explained. Bill Nye The Science Guy on Wind (Full Clip)
