During low solar activity, these particles easily reach Earth, causing heavy
cloud formation and making the planet's temperature drop.
These molecules also combine with salts and chemicals in the SSAs, limiting their ability to take up water--known as hygroscopicity--and influencing their atmospheric impacts, such as
cloud formation and radiation scattering.
When warm air rising from the sun-heated ground hits this thick layer of warm smoke, the air spreads out and convection -- the mixing and circulation of layers of air that encourages
cloud formation -- is thwarted.
This season we have seen good
cloud formation in the lower levels, but invariably it is pushed down by a high pressure layer above 25,000 feet.
Differences:
cloud formation changed, extra Canada goose in sky, flag on tent, paddle for canoe, campfire pit, a piece of driftwood in the water, decoration on cooler, wider tree trunk, picnic basket or sandcastle, butterfly position changed, squirrel or chipmunk, and spider's web or bird's nest.
Atmospheric scientists have developed simple, physics-based equations that address some of the limitations of current methods for representing
cloud formation in global climate models--important because of increased aerosol pollution that gives clouds more cooling power and affects precipitation.
"Moist air rises over warmer waters, leading to
cloud formation and rainfall," he says.
This clear and well-illustrated guide to identifying what can be seen in the sky covers cloud classification,
cloud formation, optical phenomena such as rainbows, color in the sky, visibility (mist/ fog/sea smoke), precipitation, winds, severe weather (oddly, hurricanes are included here only briefly, under tornados.
Through their research, the scientists were able to determine the composition of the spinach juice cloud and what factors influence
cloud formation. They came up with a feasible way to reduce or to prevent clouding.
Cutting down the forests reduces the amount of water available for
cloud formation and also warms the air.
The program succinctly and intelligibly explains to young viewers the fundamentals of
cloud formation, the scientific principles of dew point and relative humidity, why rising warm air is essential to the formation of clouds, the relationship between relative humidity and temperature, and the different types of
cloud formations and what weather is associated with each.
During the first night's speech I mentioned that the American Life League actually claims that Walt Disney's "The Lion King" contains the word "sex" floating by in a
cloud formation. Incredibly, a Disney animator was in the crowd and at a reception afterwards assured me that Disney does not allow that kind of artistic license.
