Latest Cloud Stories
The clouds on Mars, at first glance, might be easily mistaken for those on Earth. NASA's Opportunity rover returned images of the Martian sky with gauzy, high-altitude wisps that are similar to our cirrus clouds.
A detectable electrification of the air is caused by electrical currents born from thunderstorms. These currents flow through the atmosphere and around the globe, even in places with no thunderstorm activity.

A new study has resurrected the hypothesis that cosmic rays may influence cloud formation on Earth.
A new analysis of near-infrared images taken by NASA's Cassini orbiter is providing more data about the composition of Saturn's atmosphere.
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...
Orographic thunderstorms are formed when the air is pushed up a mountain side. This type of thunderstorm is found only on the windward side of a mountain range. In the United States we would find these types of thunderstorms on the western slopes of the Rocky Mountains and also on the western slopes of the Appalachians. Things that make this thunderstorm important: First of all they only form in certain geographical places on the earth as mentioned above. But they can form anywhere in the...
Weather Pack is our way to envision what is happening with the weather and create a weather forecast for a certain area of the United States. Today’s focus is on Southwest Mississippi along the Mississippi River. On the left side we have a Skew-T which is used to help us determine what is happening in the upper levels at our forecast location. On the right side is our morning satellite image; both of these features are important to creating an accurate forecast. The Skew-T will show...
The above map looks at what is known as ceilings. The definition of ceilings is the first broken or overcast layer of cloud cover in the atmosphere. For it to be considered a ceiling the clouds need to cover more than half of the sky. If we look at the red circled area we see the numbers of 1 and 2. This tells us that there is a ceiling at 1,000-2,000ft which are in the level of low clouds such as cumulus or stratus. The second is the black circle found in the Dakota’s. Here we are...
The image above shows a Cumulus-nimbus cloud that has an anvil top to it. The reason that can be identified is that the cirrus is in place above the center of the storm. The image below does not have an anvil top yet. The anvil top forms on CB clouds after they reach the height in the atmosphere where they begin to feel the upper level winds becoming too strong for them to continue development vertically. The storm on the right has not felt the upper level winds yet, that is why it lacks the...
