Why Koozies Keep Your Beer Cold
2013-04-26 12:01:46

Michael Harper for redOrbit.com — Your Universe Online Countless theories on the best way to quickly cool down a beer (or soda for the teetotalers) have been formed in the past, some of which were even put to the test by the MythBusters. But just as important as cooling beer is the challenge of keeping it cold, an aspect which is suspiciously absent from these frat-born theories. According to a new study published in Physics Today, a koozie is the best defense against condensation...

Weather And Climate Models Improved Using SEALDH
2013-03-04 12:15:33

Physikalisch-Technische Bundesanstalt A humidity sensor developed by the Physikalisch-Technische Bundesanstalt (PTB), the SEALDH laser hygrometer, has proven its worth when used aboard an aircraft; it fulfills all pre-conditions to be used as a transfer standard for conventional humidity-measuring instruments. This would allow the quality of air humidity measurements in the Earth's atmosphere - and, thus, also climate model computations - to be improved. Humidity measurements in the...

Is Mars Hot or Cold?
2013-02-08 14:49:48

Alan McStravick for redOrbit.com - Your Universe Online With all the attention being paid to Mars, we are learning something new about the red planet almost daily. Each new revelation is pretty heady information. But what about the weather on our celestial neighbor? One of the most common questions that people have is whether Mars is hot or cold. The early days of Earth was marked by a climate that was both warm and wet, and mirrors what Mars was like some 3.5 billion years ago....

Weather Model Discussion:  How To Use Surface Dew-points For Weather Forecasting Purposes
2013-01-29 08:53:47

Surface Dew-points can play a huge role in weather forecasting. The first such role is that it helps determine the amount of moisture in the atmosphere for a given point. If we look at the current dew-point map above from January 28, 2013 we can note several things of interest. First, if we look at where the black circle is around the number 70, we can make note that this air right off the coast of Texas is at a dew point of 70F. The temperature outside must be above 70F, because the...

The map above shows our dew-point temperatures which is an important temp when it comes to weather. The dew-points help us determine how much moisture is in the atmosphere. If we look at the circle placed over Southern Mississippi we can see temps in the Mid 70’s. That is considered to be very saturated and humid type of weather. When you walk outside it feels very uncomfortable. While if we look back in Nevada we see 15, this is more respectful of being very dry air. This type of air also...

The Heat Wave Of The Central United States
2012-06-26 06:00:45

So why is there so much heat and humidity rising up into the Northern Plains creating a surge of hot weather? The answer is in the weather map above. If we look over Lake Michigan we see an area of High pressure which has a clockwise flow over the region. So places on the East are having cooler weather as they are getting the air from Canada pushing down towards them. North Dakota into the Gulf Coast are on the back side of the high so there air is coming from the Gulf of Mexico. If...

Water vapor (aqueous vapor) is the gaseous phase of water. It is one stage of the water cycle of our planet. Water vapor is formed from either evaporation or heating of liquid water, or from the sublimation of ice. In nature, water vapor is continuously produced by evaporation and removed by condensation. Along with carbon dioxide and methane gas, water vapor is one of the greenhouse gases. The release of water molecules from liquid water is considered evaporation. The transition of these...

Haze is a type of atmospheric phenomenon where dust, smoke and dry particles in the air obscure the sky's clarity. Haze is created through various activities including farming, traffic pollution,and even wildfires. The World Meteorological Organization (WMO) categorizes the obscuration of the Earth's atmosphere by a list of different types of atmospheric phenomena. One of these is haze. The other classifications are: fog, ice fog, steam fog, mist, smoke, volcanic ash, dust, sand, and snow....
