What is Rain that freezes on the way down called?
Condensed water molecules fall out of clouds as snow. If they hit a warmer part of air (over 32 degrees F) then they melt into rain. If they hit a colder part of air before they hit the ground, but after they go through the warmer air, then they form a slushy like snow called sleet.
What temperature does the air need to be for it to snow?
The air at ground level or the air at the altitude where the snow forms? Snow forms in clouds and then falls. Therefore it can be and usually is warmer at ground level than in the clouds...Answer...water moisture freezes at 0° C or 32° F so it would have to be freezing in the clouds where the snow forms.
Who proposed the dust cloud theory?
is Carl f. Von Weizsaccker
What do the four blocks of the periodic table have in common?
they're all cloud levels... i mean orbitals the first two rows are S cloud, the middle (transition metals) is the D cloud, the six rows on the left are the P cloud and the lanthanide series is F cloud
What do you call rain that falls but does not reach the earth?
rain that evaporates before touching earth is called virga.
What causes the atmospheric air to be heated rapidly?
The positive charge fixes near the top of the cloud and the negative charge at the base. A positive shadow charge builds up on the ground beneath. An electric current is then discharged in a blinding flash as lightning zig zags between ground and cloud. A weak spark known as the stepped leader reaches down from the cloud and a positive leader rises to meet it. The main discharge called the return stroke takes place from ground to cloud along the channel created by the two leaders. We also see intra-cloud lightning within the cloud and inter-cloud lightning between clouds. When the lightning is hidden or diffused by clouds we call it sheet lightning. Air around the discharge channel is heated to about 30,000 C (55,000 F). The sound of thunder is made by heated air expanding very rapidly and causing soundwaves.
What is the difference between F 15C and F 15E?
F-15C is an air superority fighter, just fights fighters air to air, while F-15E is a fighter/bomber, can fight other fighters & bomb ground targets.
When was William F. Cloud born?
William F. Cloud was born on 1825-03-23.
When did William F. Cloud die?
William F. Cloud died on 1905-03-04.
How to calculate cloud size and height from the ground?
Current Temperature (fahrenheit) - Dew Point (fahrenheit)/4.4*1000 = Cloud base height (feet) Example: Conversion: Current Temp 17 C = 62.6 F Dew Point 12 C = 53.6 F 62.6F-53.6F/4.4*1000 = 2045 feet
What is the best aircraft the navy owns?
It depends on the mission requirement (recon, attack, ASW, EW, etc.). For pure air-air and air-ground attack roles, the F/A-18E/F Super Hornet is currently the Navy's fighter weapon of choice (E is a single seater;F is a 2 seater).
How does thunder and lightning work?
Lightning is a discharge of electrical energy that builds up within a storm. The charges develop because a storm causes air to move around which rubs against itself to generate electrical charges. Eventually the charge increases to a point where the electricity can flow through the air. Once an electric discharge starts it provides a better path for more electrical flow than normal air due to ionization which results in a sudden, large and fast discharge (i.e. a lightning bolt).Negative charges at the bottom of the clouds repel the negative charges on the surface of the earth. This leaves the surface of the earth positive (the electrons on the ground migrate to get further away from the other electrons in the cloud). From there, the negative electrons from the cloud attract the positive electrons on the ground, which pulls electrons from the air. This usually occurs at a high point on the ground.Answer:When you have a thunderstorm that forms from convection and differences in temperature across a frontal boundary, you start to get differing charges building up between the cloud base and the ground. When the difference in charge gets great enough between the cloud base and the ground, the air becomes a conductor instead of being an insulator and a negatively charged stepped leader comes down from the cloud base and meets a positively charged return stroke from the ground. When this happens, we see visible lightning and positive charge is carried up into the cloud base, while negative charge is carried down into the ground, essentially it is a transfer of both of the charges involved in the electrical discharge. This lightning strike is called a negative strike because the stepped leader is negatively charged. There is also something called a positive lightning strike, where enough differing charge builds up between the top of the cumulonimbus cloud and the ground and the same transfer of positive and negative charges happens, but the stepped leader from the top of the cloud in this case is positively charged and the return stroke from the ground is negatively charged. Initially the top of the cloud is positively charged, the cloud base is negatively charged, and the ground is positively charged. Positive strikes are possible after several negative strikes between the cloud base and the ground have happened. Lastly, lightning strikes can go out a maximum of 10 miles ahead and behind the storm, so remember just the because it looks like the storm has passed, doesn't mean the threat of lightning doesn't exist.

What are the primary differences between an F-15 and an F-16?
There are two primary differences between these two aircraft. Visibly the F-15 is a multiengine fighter utilize side by side engines for propulsion. The F-16 only has a single engine. Secondly, their role. F-16's are true air to air combat airplanes created with high mobility for dog fighting or air to air combat. F-15's are designed more on a multi role platform for uses in air to air, and air to ground attack. Less agile, yet far smore sturdy the F-15 is a more reliable attack variant.
