NASA Ex-cyclone Haruna is expected to dissipate in the Southern Indian Ocean under increasing wind shear in the next day or two. Infrared imagery from a NASA satellite shows that Haruna is being blown apart several hundred miles away from La Reunion Island. Wind shear has been a problem for Haruna for days. A night-time image from the VIIRS instrument aboard NASA-NOAA's Suomi NPP satellite taken on Feb. 21 at 22:23 UTC showed the eye of Cyclone Haruna had elongated from northwest to...
Daily weather forecast and wrap-up provided by redOrbit meteorologist Joshua Kelly. redOrbit Meteorologist Joshua Kelly Big Story Weather from February 25: The winter storm in the Central and Southern Plains is the big story of the last 24 hours. There were reports in Amarillo Texas of 17 inches of snow and it’s still snowing out there. There was a smaller scale severe weather outbreak that did impact the Gulf Coast again yesterday with plenty of rain as some places along the...
Brett Smith for redOrbit.com - Your Universe Online Climate change may be somewhat of a philosophical or political debate, but according to a new study from the National Oceanic and Atmospheric Administration (NOAA) the debate may soon become a financial one, as well. Workers who labor without the benefit of air conditioning have already seen the amount of work they can do in the worst heat cut by about 10 percent in the past six decades due to rising temperatures, according to NOAA’s...
Daily weather forecast and wrap-up provided by redOrbit meteorologist Joshua Kelly. redOrbit Meteorologist Joshua Kelly Big Story Weather from February 22-24: A major winter storm has taken aim at the Southern Plains bringing very heavy snowfall to Western Texas and Oklahoma. On the front side in the warm sector, severe weather has been occurring over places like Louisiana and Mississippi with some places just last night getting hail the size of golf balls and rainfall rates around 4...
redOrbit Staff & Wire Reports - Your Universe Online A newly-developed National Oceanic and Atmospheric Administration (NOAA) climate model predicts that increasing carbon dioxide (CO2) levels will lead to less snowfall in most areas of the world – including the United States – over the next 100 years. In fact, research conducted by Sarah Kapnick of the Princeton University Atmospheric and Oceanic Sciences (AOS) program and Thomas Delworth, a senior physical scientist at the...
Daily weather forecast and wrap-up provided by redOrbit meteorologist Joshua Kelly. redOrbit Meteorologist Joshua Kelly Big Story Weather from February 21: A major winter storm moved through the Central Plains dumping over one foot of snow for many places in Kansas and Missouri along with parts of Nebraska. This storm then moved into Iowa and the Northern Plains. Some severe weather developed over Eastern Texas, Northern Louisiana and Central Mississippi with a few tornadoes and wind...
BOULDER, Colo., Feb. 21, 2013 /PRNewswire-USNewswire/ -- Applying its atmospheric expertise to solar energy, the National Center for Atmospheric Research (NCAR) is spearheading a three-year, nationwide project to create unprecedented, 36-hour forecasts of incoming energy from the Sun for solar energy power plants. The research team is designing a prototype system to forecast sunlight and resulting power every 15 minutes over specific solar facilities, thereby enabling utilities to...
NASA/Goddard Space Flight Center Cyclone Haruna strengthened into a cyclone and quickly developed an eye that became apparent on visible and infrared imagery from NASA's Aqua satellite. NASA's TRMM satellite analyzed Haruna's heavy rainfall, and NASA and NOAA's Suomi NPP satellite captured a night-time image that verified the strongest areas of the storm. On Feb. 20 at 1111 UTC (6:11 a.m. EST/U.S.) the AIRS instrument aboard NASA's Aqua satellite captured this infrared image of Tropical...
Daily weather forecast and wrap-up provided by redOrbit meteorologist Joshua Kelly. redOrbit Meteorologist Joshua Kelly Big Story Weather from February 20: Heavy snowfall over the Southwest tops all stories from yesterday as blizzard like conditions were seen in Arizona. Places like Phoenix that don’t often see snow got quite a bit of the white stuff. The other story was the colder air that has been in place over the Eastern two-thirds of the United States these past few days....
NASA/Goddard Space Flight Center Tropical Storm Haruna came together on Feb. 19 in the Southern Indian Ocean and two NASA satellites provided visible and infrared imagery that helped forecasters see the system's organization. A low pressure area called System 94S developed on Friday, Feb. 15 in the northern Mozambique Channel. Over the course of four days System 94S became more organized and by Feb. 19 it became Tropical Storm Haruna. On Tuesday, Feb. 19, Tropical Storm Haruna had...

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...
Desertification is a form of land degradation in which a comparatively dry land area becomes more and more arid, normally losing its bodies of water along with its wildlife and vegetation. This is a result of a variety of factors, such as climate change and human activities. Desertification is an important global, ecological, and environmental issue. There is substantial controversy over the proper definition of the term “desertification”. The most broadly accepted of these is that of...
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...
