NASA Sees System 91S Struggling
2014-01-31 14:20:56

NASA/Goddard Space Flight Center NASA's Aqua satellite provided infrared data on System 91S in the Mozambique Channel that showed a system battered by wind shear, stretched out, with broken convection. A false-colored infrared image was created at the Naval Research Laboratory in Washington, D.C. using infrared data from the MODIS instrument aboard NASA's Aqua satellite on January 31 at 11:05 UTC/6:05 a.m. EST. The MODIS image showed the strongest thunderstorms associated with System...

Invasive Pests Compromise Native Trees' Ability To Recover From Guam's Severe Storms
2014-01-31 14:13:15

American Society for Horticultural Science Guam experiences more tropical cyclones than any other state or territory in the United States. These cyclones--called typhoons in the western Pacific Ocean--can be devastating to Guam's dense native forests. The impact of large-scale tropical cyclones affects the health of managed and unmanaged forests, urban landscapes, and perennial horticulture plantings for many years after the actual storm. In fact, the island's forests are often called...

NASA Sees Tropical Cyclone Dylan Making Landfall In Australia
2014-01-30 16:05:31

NASA NASA's Aqua satellite passed over Tropical Cyclone Dylan and captured both visible and infrared imagery of the storm as it began landfalling. The visible image showed the extent of the storm, while the infrared data looked at the temperature of cloud tops to determine strong storms were already affecting the coast. The southwestern side of the storm had already started to make landfall in Queensland. Two instruments that fly aboard NASA's Aqua satellite were working to gather data...

BOULDER, Colo., Jan. 29, 2014 /PRNewswire-iReach/ -- According to a new study, Global Weather Corporation (GWC) provides the world's most accurate temperature forecasts. ForecastWatch, the leader in third-party weather forecast accuracy assessment, reports that GWC forecasts have the lowest error of those reviewed in both the U.S. and Europe for the period 1-9 days, using a metric of daily high temperature. A relative newcomer to the weather industry, GWC is included among the...

TRMM Satellite Looks At Rainfall In Developing Low Near Mozambique
2014-01-29 14:26:54

NASA/Goddard Space Flight Center The TRMM satellite flew above a System 91S, a tropical low pressure area, in the Mozambique Channel on January 28, 2014 at 1011 UTC/5:11 a.m. EST. TRMM data collected with this pass may be helpful in evaluating this low for possible tropical cyclone formation. An analysis of rainfall from TRMM's Microwave Imager (TMI) and Precipitation Radar (PR) instruments are shown on the left overlaid on a visible/infrared image from TRMM's Visible and InfraRed...

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...
