The extreme cold weather observed across Europe and the east coast of the US in recent winters could be partly down to natural, long-term variations in sea surface temperatures, according to a new study published today.
On April 2, 2014, the sun emitted a mid-level solar flare, peaking at 10:05 a.m. EDT, and NASA's Solar Dynamics Observatory captured imagery of the event.
Natural fluctuations in the ocean temperature in the North Atlantic have a significant impact on the climate in the northern hemisphere.
Wearing a high-tech impact resistant suit to ensure survival, innovator Steve Green unveils plans to become the first man to intentionally walk into a tornado CANTON, Ohio, April 1,
The National Institute of Standards and Technology (NIST) has released the final report on its technical investigation into the impacts of the May 22, 2011, tornado that struck Joplin, Mo.
Pioneering new research from the University of Exeter could have a major impact on climate and environmental science by drastically transforming the perceived reliability of key observations of precipitation, which includes rain, sleet and snow.
During the Northern Hemisphere's growing season, data returned from satellite sensors shows that the Midwest has more photosynthetic activity than any other region of the planet, according to a recent NASA report.
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 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...
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...
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...
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...
