Cloud Droplet Formation Rate Not Affected By Pollution
2013-02-19 05:21:23

A little bit of oily and viscous organic material doesn't seem to matter much when it comes to forming the droplets that make up clouds. This is good news for reducing the uncertainty of climate model predictions.

Certain Volatile Gases Found To Promote Cloud Formation
2013-02-05 09:20:34

A new study from Columbia Engineering and the Georgia Institute of Technology shows – for the first time – certain volatile organic gases can promote cloud formation in ways atmospheric scientists have never before considered.

Hailstones Full Of Bacteria And Organic Chemicals Says Study
2013-01-24 14:35:40

According to a study published in the online journal PLOS ONE, there is a rich diversity of bacteria life and organic chemicals found in hailstones in the ephemeral habitat of a storm cloud.

Dense Cloud Defies Rules Of Star Formation
2013-01-13 09:53:05

An unusually dense cloud located near the center of the galaxy does not appear to be forming any massive stars.

Major Midwestern Snowstorm Seen In Infrared Light By NASA
2012-12-21 17:01:31

NASA and NOAA satellites have been providing data on the powerful low pressure area that dropped more than a foot of snow in some Midwestern states and prompted many warnings and weather advisories.

Climate Change Threatens Cloud Forest Ecosystem
2012-12-14 08:32:14

Researchers have discovered that tropical montane cloud forest trees drink water from clouds, directly through their leaves, but the clouds necessary for the trees survival are disappearing due to climate change.

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 - Orographic Thunderstorms
2013-01-13 09:40:16

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 For July 30, 2012
2012-08-01 12:22:59

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...

Surface Analysis Features
2012-09-03 16:09:19

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...

Cumulus-nimbus Clouds
2014-01-11 00:00:00

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...
