What clouds has flat bottoms and often indicate fair weather?
Cumulus clouds have flat bottoms and often indicate fair weather. These fluffy, white clouds typically form on sunny days when the air is rising and there is no threat of precipitation or storms.
What is the density of the thermosphere?
The density of the thermosphere is extremely low, with only a few particles per cubic centimeter. This is because the thermosphere is the outermost layer of Earth's atmosphere, where gases are highly dispersed due to the low pressure at such high altitudes.
What role does water play in cloud formation?
Frankly this question is akin to asking what role water plays in streams, puddles, rivers, lakes, rain, or steam; Clouds are made up of water droplets tiny enough to be suspended in the sky by air currents. No water = no clouds.
What clouds will predict good weather?
Cirrus clouds, which are high-altitude wispy clouds, are often associated with good weather. They indicate fair weather and typically do not produce precipitation. When you see cirrus clouds in the sky, it usually means that you can expect stable and pleasant conditions.
What causes jet streams to blow?
Jet streams are fast moving belts of wind high in the atmosphere- there are two of them in the hemisphere, with the Polar Jet being the stronger of the two. The reasons for its existence are twofold: one being the rotation of the Earth causes angular momentum to be transported to higher latitudes whereupon it is basically "released" and returned to the Earth via the jet stream. The subtropical jet stream owes its existence to this as well as the mechanism of this momentum transport from the Tropics - via large-scale eddies in the atmosphere (largely, the Hadley Cell). The eddy flux of zonal (west-east) momentum peaks at about the tropopause level at 35 degrees latitude, where it is poleward in both hemispheres and strongest in winter.
What are the different names of clouds?
Hope this helps !
Cumulus, which looks like cotton or whipped cream.
Stratus, looks like a flat blanket in the sky.
Cirrus, looks like curls of white hair.
What pressure system is more likley to be associated with clear conditions?
High-pressure systems are more likely to be associated with clear conditions. High pressure typically brings stable air, which suppresses cloud formation and leads to clear skies.
What does the characteristic flat base of cumulus clouds represent?
The flat base of cumulus clouds typically represents the level where the rising warm, moist air meets a stable layer of air that prevents further vertical growth. This often indicates the boundary between the convective boundary layer and the stable atmosphere above, creating the distinct appearance of cumulus clouds.
Why clouds form over mountains?
Clouds form over mountains when moist air is forced to rise due to air flow patterns and the topography of the mountain. As the air rises, it cools, causing the moisture it contains to condense into water droplets, forming clouds. This process is known as orographic lifting.
What is the name of a regular rain or snow cloud?
the name of the cloud full of rain isz cumulus....misz.remynisce
What happens when solid water gradully changes to water as a gas?
Solid water (ice) changes to water vapor through the process of sublimation, where it goes directly from a solid to a gas without melting into a liquid first. This occurs at temperatures below the melting point of ice, typically caused by heat or reduced air pressure.
Why does high pressure mean good pressure?
high pressure makes good weather because the air mass rises
What develops when a cold air mass and a warm air mass collide and neither of the air masses move?
Another has properly said - A Stationary Front. Adding that, when movement recommences the cold Air Mass will invariably subside below and then underneath the warm Air Mass.
A good and easy lesson on the causes of Rainfall is that wherever Air rises Clouds form - Air rises, it expands, it cools and can no longer hold as much Water Vapor - and it Rains.
When the relative humidity is 100 percent the air temperature is equal to the dew point temperature?
Yes, when the relative humidity is 100 percent, it means the air is holding the maximum amount of moisture it can at that temperature. At this point, the air temperature is equal to the dew point temperature, causing condensation to form as the air becomes saturated with moisture.
What does a cumulonimbus cloud produce?
A cumulonimbus cloud can produce heavy rainfall, lightning, thunder, and sometimes hail. They are associated with severe weather events such as thunderstorms, tornadoes, and heavy downpours.
What is the electrical discharge between a cloud and the ground?
The electrical discharge between a cloud and the ground is known as lightning. It occurs when there is a difference in electrical charge between the cloud and the ground, and is typically accompanied by a bright flash and thunder. Lightning is a powerful natural phenomenon that can be dangerous and destructive.
Why is dew point better measurement of water vapor than relative humidity?
Because relative humidity changes with temperature. Air at 30 F and 90% humidity actually is holding less water than air at 90 F and 20% humidity. Dew point will give you a better idea of how much moisture is in the air because it doesn't change with temperature. For example, dew points in the 70's will always feel very sticky and uncomfortable because that is a lot of moisture in the air.
What does water vapor do in the water cycle?
The processes are called "evaporation" and "transpiration".
The damage from a microburst appears to radiate out from the center while tornado damage occurs along the path that the tornado took. In a microburst trees fall or are bent outwards, with trees that neighbor each other generally falling in the same direction. In a tornado downed trees to not have the same order, and fall in multiple directions. Those left leaning may hint towards an inward or rotating flow. Some tornadoes have roughly crescent shaped areas of more severe damage, indicating a multivortex structure.
What is dew point and how do you know the temperature has reached its dew point?
Dew point is the temperature at which air becomes saturated with water vapor and condensation begins to form. You know the temperature has reached its dew point when water vapor in the air begins to condense into liquid water, such as dew on the ground or fog in the air.
How are land breezes and sea breezes related?
Land breezes and sea breezes are both types of local wind patterns that are caused by the temperature difference between land and water. During the day, land heats up more quickly than water, creating a low-pressure area over the land and a high-pressure area over the water, resulting in a sea breeze blowing from the water to the land. At night, the land loses heat faster than water, creating a high-pressure area over the land and a low-pressure area over the water, leading to a land breeze blowing from the land to the water.
What is the role of nuclei in condensation?
Nuclei in condensation act as sites where water vapor molecules can come together and form droplets. These nuclei provide a surface for water vapor to condense onto, initiating the process of condensation. Without nuclei, condensation would have a harder time starting, and mist or fog formation would be delayed.
What do green clouds in a thunderstorm mean?
Green clouds in a thunderstorm can indicate the presence of hail or strong updrafts within the storm cloud. This color is caused by sunlight filtering through the moisture in the air. It does not necessarily mean a tornado is forming, but it is a sign of turbulent weather conditions.
