Heavy Rain Continues In Tropical Cyclone Amara
2013-12-20 14:10:58

NASA/Goddard Space Flight Center NASA's TRMM satellite saw heavy rainfall was happening in Tropical Cyclone Amara on December 16, and still occurring on December 19, although it moved from east to southeast. Warnings are already in effect for Mauritius' Rodrigues Island. NASA's Tropical Rainfall Measuring Mission or TRMM satellite can measure rainfall rates from space, and that's what it has been doing over Tropical Cyclone Amara since it was born. On Dec. 16, at 2043 UTC/3:43 p.m. EST...

NASA Sees Wide-eyed Tropical Cyclone Bruce
2013-12-20 14:06:51

NASA/Goddard Space Flight Center Tropical Cyclone Bruce was still maintaining hurricane-force in the Southern Indian Ocean when NASA's Terra satellite passed over the eye of the storm. The Moderate Resolution Imaging Spectroradiometer instrument known as MODIS takes amazing visible and infrared images of tropical cyclones, among other things, and captured a good look into the eye of Bruce on Dec. 19 at 03:41 UTC. Although Bruce's eye seemed to have some high clouds, the eye was still...

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...
