Infectious capacity of influenza virus particles reduced at relative humidity of 40 percent or higher Higher humidity levels indoors can significantly reduce the infectivity of influenza virus particles released by coughing, according to research published February 27 in the open access journal PLOS ONE by John Noti and colleagues from the National Institute for Occupational Safety and Health, Centers for Disease Control and Prevention. The researchers tested the effect of relative...

The Arctic is getting warmer and wetter. As temperatures rise and sea ice melts, scientists suspect that system feedback cycles may further speed up the warming process. Now, a new study out of the University of Colorado at Boulder is showing how shifting patterns of humidity may bring about changes in the Arctic atmosphere. The new study compiled data from the 1950s through the present to examine the subtle changes in the Arctic atmosphere over time. The team then incorporated the data...

Brett Smith for redOrbit.com — Your Universe Online Using a “non-stationary” model that factors in the recent warming trends of the past few years, researchers from the Scripps Institution of Oceanography at UC San Diego have determined that California heat waves will become more humid and stronger in populous coastal areas. Traditionally, California heat waves primarily affect the interior desert and valley areas that become hot during the day and both cooler and...

Michael Harper for redOrbit.com — Your Universe Online Humans are fascinated with the weather. It gives us something to talk about when there´s not much to say and it gives us something to collectively despise when it begins to act up. We even act strangely in times of bad weather, exhibiting behavior such as standing on the back porch staring into the clouds during a tornado watch or instinctively rushing to the grocery store whenever rain approaches. While many have no...

Urban Heat Island
2013-04-02 15:35:21

An urban heat island (UHI) is a metropolitan area that is drastically warmer than its surrounding rural areas because of human activities. The phenomenon was first looked into and described by Luke Howard during the 1810s, although he wasn’t the one to name the phenomenon. The difference in temperature is normally bigger at night as opposed to during the day, and it most obvious when winds are weak. Seasonally, UHI is seen during the summer and the winter. The key cause of the urban heat...

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

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...

White frost is a type of solid ice that forms directly from water vapor found in the air. White frost forms when the humidity is above 90% and the temperature is below 18 degrees Fahrenheit. White frost grows against the wind, since the facing winds have higher humidity than leeward air. The wind must be light or the delicate icy structures become broken. The structures have big, interlocking, needle-like crystals. This phenomenon occurs very rarely. White frost is considered an intermediate...
