Understanding atmospheric pressure
By: Jose Juan Gutierrez
Atmospheric pressure refers to a mass of air in the atmosphere, exerting weight over a unit of area. The pressure of air at any level in the atmosphere is measured by the total mass of air above any point. The density of air is greatest...
What is the greenhouse effect?
By: Jose Juan Gutierrez
The greenhouse effect is the natural process by which the Earth´s atmosphere captures some of the Sun´s radiation wavelengths, warming the Earth´s surface sufficiently enough to support life; however, human activities, including the burning of fossil fuels and deforestation have contributed to...

Methane is a concern for climatologists as it is a detrimental greenhouse gas. Yet, methane is natural. Only the concentration of it in recent post-industrialization is problematic. Methane in the atmosphere has effectively doubled in the last two hundred years. The fact is that methane...

Isobars are lines that depict areas of equal and constant pressure at the Earth’s surface or at a constant height above it on a meteorological map. Each line passes through a pressure of a given value, but they can never cross or touch. Isobar...

“Often shalt thou confirm thine airspeed on final lest the earth rise up and smite thee.” (Commandment number 10 of the Pilot's Ten Commandments.) Airspeed is the velocity at which an aircraft is traveling relative to the air mass in which...

While most people flee in terror from tornadoes, hurricanes, gale-force winds and other ferocious forms of weather, storm chasers happily plunge themselves directly into Mother Nature's treacherous pathways. Not only do they do this for the adrenaline rush and their quest for knowledge, but for...
Understanding why water vapor is the most abundant greenhouse gas
By: D. Vogt
Although governments and scientists are currently worried about the role which carbon dioxide and methane emissions play in global warming, perhaps somewhat surprisingly, the most important greenhouse gas today is actually water vapour. Recent research has confirmed that, although the rise in carbon emissions is...

Before talking about why water vapor is the most abundant of the greenhouse gases, it is a good idea to know what makes a gas a “greenhouse gas” (GHG) in the first place. It's also wise to know what a GHG does. Beyond that...

There’s more than one reason some people chase deadly storms, and perhaps some of the reasons for it have yet to actually be reported on news outlets or discovered. For one thing, people that have taken up storm chasing as a profession aren’t...
Reason why people chase deadly storms
By: Cameron Scott
Weather watchers know that there’s nothing like seeing a fascinating storm first-hand. Storm chasers take that fascination a step further. For them, it’s not enough to wait for a strong storm to come to them. They’ve got to go out there and...
