What weather instrument is used to measure floods?
There is no such thing as an instrument that measures floods but there is an instrument that measures rain which is called a rain gauge, and an instrument that measures how deep the water is at a given location which is called a river gauge.
Satellite imagery is usually used to measure the magnitude of floods. Topographic maps are used with the imagery before and after a flood to estimate how deep and widespread the flooding is. It surprisingly accurate given the large area of coverage.
Clouds are constantly forming and disappearing as the atmospheric conditions change. From the wording of your question, however, it seems that you wish to know why clouds stay in the atmosphere and don't actually waft off into outer space. Clouds are made of water droplets that coalesce around tiny dust particles. They will rise to an altitude where their buoyancy equals their weight. At high altitudes, even the least dense, most buoyant clouds can no longer rise, because the atmosphere is so thin. Cirrus clouds are high-altitude clouds formed from ice crystals. They usually form above 16,000 feet. Cumulonimbus clouds are vertical-forming clouds that reach altitudes of 60,000 feet. They are associated with thunderstorms.
What causes the water vapor to lose its energy?
When it clings to a nearby cold glass, water vapor loses it's energy and turns into tiny water droplets on the outside of the cold glass. This is called condensation. You may have noticed it before. If not, next time you have a cold glass of water or pop, wait for a little bit, then look at the outside of the glass.
Why is there a bimodal distribution of elevations on the surface of the earth?
The bimodal distribution of elevations on Earth's surface is due to the presence of both ocean basins and continental landmasses. The ocean basins are generally lower in elevation, while the continental landmasses have higher elevations, resulting in the bimodal distribution commonly observed.
What state of matter are clouds?
Although many people think they are in solid form or water vapor, clouds are actually liquid water. It's impossible for them to be water vapor, because vapor is invisible. Clouds are not invisible.
Can a weather map and weather symbols be used to forecast the weather accurately?
That is what meteorologists use to show us what is going on with the weather and what weather to expect. The map and symbols that you see on the television are only a very small part of how they come up with a forecast. There are weather models and different weather data that they use to actually come up with the forecast and make the map you see on television.
Does it take longer for water to change temperature than land?
Yes, water has a higher specific heat capacity than land, which means it takes longer for water to change temperature compared to land. This is because water requires more energy to raise its temperature by one degree Celsius.
Water vapor form snowflakes when the temperatures in the air are above freezing and the air should be unsaturated. The water vapor to create hailstones start inside a cumulonimbus cloud and super cooled liquid water are caught in a strong updraft. The cycle continues to increase the size of the hailstone, then eventually falls to the earth's surface.
Thunderstorms start usually along a frontal boundary usually assoicated with a cold front but sometimes can happen with the other types of fronts. Along a cold frontal boundary, warm moist air is lifted up and over the cold air mass sitting behind the front. The warm moist air being uplifted along the frontal boundary cools by expansion and the moisture is condensed into clouds. Now here is where the fun part begins, the warm moist air that was uplifted along the cold frontal boundary is uplifted by updraft winds that continue expansional cooling and condensation upwards vertically. Usually before you see the thunderstorm mature you will start to see fair weather cumulus clump together into whats called cumulus congestus. Cumulus congestus are mash potato shaped heaps of cumulus clouds that are coming together and are getting shot upwards in vertical motion by updraft winds. When a thunderstorm reaches maturity, it reaches the upper troposphere and the top of the thunderstorm cloud is ripped apart by the upper level jetstream into anvil cirrus clouds which are then carried downstream of the storm by the upper level jetstream. Before a thunderstorm matures, downdraft winds form in the front of the storm carrying precipitation and sometimes downbursts out of the storm. Once a thunderstorm runs out of moisture and energy, it starts to dissipate and weaken and eventually dies out all together.
When a gas changes into a liquid, it undergoes condensation. This process occurs when the gas loses energy (usually in the form of heat) and its particles slow down and come together to form a liquid. The opposite process, when a liquid changes into a gas, is called vaporization.
What is the third scientific principle that is essentail to cloud formation?
The third principle is: Hot air rises. This allows moisture in the air to condense when it hits colder air, making clouds.
What is April weather like in Georgia?
The weather in Georgia is not great during April.
We just moved from a Northeastern state and now always living in fear of Tornado watches/warnings every time it rains.
Isolated thunderstorms are never isolated and chance of precipitation less than 30% is never less than 70%.
People say it was not like this in Georgia but I cant believe in what they say nor is it going to get any better with weather changes around the world.
What is formed when water vapor cools?
Condensation.
Nothing is actually formed, the water vapour changes state to liquid water. Condensation is the process by which the change takes place rather than the product of the cooling.
Where is the atmospheric pressure the greatest?
The atmospheric pressure is greatest at sea level, where the weight of air above is at its highest due to gravity pulling air molecules towards the Earth's surface. As you move to higher altitudes, atmospheric pressure decreases because there is less air above exerting pressure downwards.
Which cloud rarely extend to the stratosphere?
Moisture is rare in the stratosphere, so few clouds reach this location. Nacreous and non-nacreous clouds are the only category of clouds found in the stratosphere, and the non-nacreous ones contain nitric acid.
How do different solutes affect boiling point?
When a solute is added to a solvent, the boiling point is raised according to the equation ΔTb=Kbm. Thus, the boiling temperature of a solution can be described by: Tb(solution)=ΔTb + Tb(pure solvent).
However, for the purposes of this question, adding a solute increases the boiling point of a solution.
Which constant pressure charts are suitble for locating the position of jet streams?
You may want to consider looking at the high level prog charts to get an idea of the jet streams' (there can be more than one) location and speed. Check the link below. http://aviationweather.gov/products/swh/
What is the opposite of every cloud has a silver lining?
Clouds technically can have 'silver linings' generally caused by light when the sun is just behind them, causing the top layer of the cloud to look lighter as its thinner and less dense than the rest of the cloud, and sometimes the silver linings can be slightly blinding as the light can reflect off the water droplets and go into your eyes.
How does temperature affect air pressure?
As temperature increases, air molecules move faster and spread out, causing air pressure to decrease. Conversely, as temperature decreases, air molecules slow down and come closer together, leading to an increase in air pressure. This relationship is known as Charles's Law.
Well actually you can't really touch a cloud. But it's strange that you can walk through it. You don't feel anything besides maybe a puff of air.
Not technicly but fog and mist are the clouds just at our level. It feels damp. :)
Clouds are composed of water droplets or ice crystals suspended in the atmosphere. While you may not be able to physically touch a cloud, they are soft and fluffy in appearance, often described as feeling light and airy.
Process that is the source of the suns energy?
The process that is the source of the sun's energy is nuclear fusion. In the sun's core, hydrogen atoms combine to form helium, releasing a large amount of energy in the form of light and heat. This process sustains the sun's energy output and provides the warmth and light that sustains life on Earth.
When does a cloud stop rising?
A cloud stops rising when it reaches a height in the atmosphere where the air temperature is equal to or cooler than the temperature of the rising air in the cloud. At this point, the cloud's upward motion halts and it spreads out horizontally.
Can going barefoot before the weather is warm make you sick?
Going barefoot in cold weather can lead to a higher risk of getting sick, as exposure to cold temperatures can suppress the immune system and make you more susceptible to illness. Additionally, walking barefoot in cold and damp conditions can increase the risk of catching a cold or the flu through direct contact with viruses on the ground. It is important to keep your feet warm and protected, especially in cooler weather, to help prevent illness.
What is the role of air pressure in weather formation?
Air pressure plays a crucial role in weather formation by driving the movement of air masses. Differences in air pressure lead to the development of high and low-pressure systems, which in turn influence wind patterns and weather conditions. Areas of high pressure generally bring fair weather, while low-pressure systems are associated with stormy conditions.
