University of Exeter New study shows drought, heat waves and cold spells linked to air flow changes Variations in high-altitude wind patterns expose particular parts of Europe, Asia and the US to different extreme weather conditions, a new study has shown. Changes to air flow patterns around the Northern Hemisphere are a major influence on prolonged bouts of unseasonal weather – whether it be hot, cold, wet or dry. The high altitude winds normally blow from west to east around...

2014-06-16 04:41:53

redOrbit Staff & Wire Reports - Your Universe Online Despite the fact that many parts of the United States experienced extremely cold conditions this past winter, the risk of such conditions increasing as a result of climate change is unlikely, according to research appearing in the latest edition of Nature Climate Change. Study author Dr. James Screen of the University of Exeter reports that the Arctic amplification phenomenon, which refers to the increased warming rate experienced...

Despite Inhospitable Temperatures, Mars Lacks Frigid Wind Chills
2014-06-13 13:14:52

Brett Smith for redOrbit.com - Your Universe Online While the average planet-wide temperature on Mars is a frigid -81 degrees F and the lowest winter temperatures can get down to -184 degrees F, the Red Planet is much more hospitable than those temperatures would suggest due to a lack of wind chill, a new study has found. The wind chill temperature on Earth is always colder than the thermometer reading, but on Mars the temperature would feel as much as 200 degrees F hotter than the...

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...

Climate Change
2013-04-01 11:05:27

Climate change is a substantial and lasting change in the statistical distribution of weather patterns over periods of time ranging from decades to millions of years. It might be a change in the average weather conditions, or in the distribution of weather around the average conditions. Climate change is a result of factors that include oceanic processes, biotic processes, variations in solar radiation received buy Earth, volcanic eruptions, and plate tectonics, and human induced alterations...

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...

Weather Education - Air Mass Thunderstorms
2013-01-13 10:30:47

Air mass thunderstorms are found in marine time tropical air. In short they are also known as MT Thunderstorms. Air mass thunderstorms represent what is known as the common three stage thunderstorm development. This means that an air mass thunderstorm goes through the stages of Cumulus which is represented by the updrafts only being present; secondly it moves into the mature stage where it has both updrafts and downdrafts; finally it goes into the dissipating stage where you see only the...

Weather Education - Super-cell Thunderstorms
2013-01-13 09:51:18

In this lesson we are going to take a look at super-cell thunderstorms and what they mean and how they impact our daily lives. First, a super-cell thunderstorm is formed from a cumulus-nimbus cloud.  Super-cell thunderstorms are the most advanced form of thunderstorms known on earth. This is because these types of thunderstorms need so many things to come together in the atmosphere at the same time. The first thing they need is the warm moist air at or near the surface. Secondly, is...
