Clouds

A cloud is a visible body of very fine water droplets or ice particles suspended in the atmosphere at altitudes up to several miles above sea level. They are generally produced by the condensation of water vapor. Other clouds, less commonly seen, are composed of smokes or dusts.

As you walk down a mountainside atmospheric pressure will what?

It will increase. Atmospheric pressure decreases with altitude and increases as you move toward sea level. At sea level, atmospheric pressure = 1.0

What is a Warm or hot air blowing device?

A warm or hot air blowing device is typically a heater that uses electricity, gas, or another fuel source to generate heat. It blows out warm or hot air to heat up a specific area or room for comfort or to maintain a desired temperature. Examples include space heaters, furnaces, and hair dryers.

Does Higher humidity makes you sweat more?

Yes, higher humidity can make you sweat more because sweat is less likely to evaporate quickly in humid conditions. This can make you feel hotter and more uncomfortable as your body works harder to regulate its temperature through sweating.

What will happen when the temperature falls further than the dew point temperature?

Cooling air below the dew point will result in the water in that air coming out of solution to deposit itself on surfaces. We call that dew. Certainly as the temperature continues to fall, it may even cause rain (if it isn't too cold).

What indicates fowl weather is approaching?

A drop in air pressure, increased cloud cover, darkening skies, and wind shifts are all indicators that foul weather, such as storms or heavy rain, may be approaching. Animals behaving unusually, such as seeking shelter or becoming noisy, can also signal approaching bad weather.

Where in the US do the deepest low pressure systems form?

The deepest low pressure systems in the US typically form in the central Great Plains region, known as "Tornado Alley." This area experiences a collision of warm, moist air from the Gulf of Mexico and cold, dry air from the north, creating conditions for intense low pressure systems to develop.

What is the scientific name of stratus rain clouds?

The scientific name for stratus rain clouds is "nimbostratus." These clouds are low, thick clouds that often bring continuous rain or snow.

Do both rain and snow begin as ice crystals?

Snow does, but rain does not have to. Rain can start through two processes, which are called "collision-coalescence" and "the Bergeron process". The former is the one by which rain never begins as ice, and this is most common in the tropics and in higher latitudes during the warm season.

What are the various factors which influence the evaporation of a liquid?

Factors influencing the evaporation of a liquid include temperature, surface area exposed, humidity of the surrounding air, and the presence of air movement (wind). Higher temperatures, larger surface areas, lower humidity, and increased air movement all accelerate evaporation.

Do trees help clouds to form?

They can in a way, though it's not easy to measure. The best example is over the Amazon Rain forest where there is so much vegetation transpiring moisture back to the atmosphere under the intense, year-round sun that this aids in the formation of clouds and subsequent precipitation. In this case, it has been very clearly shown that without the forest there, a significantly smaller amount of rain (and therefore clouds) would fall/form. This is being observed as the rain forest is being cut down and transformed into pasture.

However, outside of this type of environment (for example, the mid-latitudes), I wouldn't really say that clouds get much help from surface vegetation.

In the summer does the continental tropical air mass form over Mexico and brings dry hot air to southwestern US?

Yes, the continental tropical air mass often forms over Mexico during the summer months, bringing dry and hot air to the southwestern United States. This air mass originates from the hot desert regions of northern Mexico and can lead to high temperatures and a lack of moisture in the affected areas.

Water is not used as barometric liquid?

Mercury is having a higher specific density ( about 13 times that of water) . So if we want to make a barometer using water it should be at least 13 times the length of mercury barometer that is about 11m so it is advisable to use mercury as a barometric liquid.

Is classification air mass based primarily on temperature or precipitation?

Classification of air mass is primarily based on temperature. Air masses are classified as maritime or continental based on the source region's temperature and humidity characteristics, with precipitation playing a secondary role in determining their classification.

What can water in clouds undergoes condensation lead to?

When water in clouds undergoes condensation, it forms into small water droplets or ice crystals. These droplets or crystals may combine and grow larger, eventually becoming heavy enough to fall as precipitation in the form of rain or snow.

Evaporation occurs when two fronts of widely different moisture levels meet?

Evaporation is actually the process by which liquid water changes into vapor and moves into the atmosphere. When air masses with different moisture levels meet, it can lead to the formation of clouds, precipitation, or changes in weather patterns, but this is not directly related to evaporation.

Whic unit measure atmospheric pressure?

Atmospheric pressure is typically measured in units of millibars (mb) or kilopascals (kPa). The standard unit for atmospheric pressure is the pascal (Pa), with 1 atmosphere being approximately 1013.25 hPa or 101.3 kPa.

What does it mean when the sky is yellow during a thunder storm?

The sky can change various colors depending on whether its night or day. During a thunderstorm the sky will change to a bright illuminating yellow or orange when its a severe storm. The reason behind that is actually unknown. However some experts say its depending on the heated temperature high up in the atmosphere that storms can actually cause many different storm colored skies. For instance, tornadoes usually can cause a green yellowish color when approaching.

Consider a steaming aluminum soda pop can that contains a small amount of boiling water when it is quickly inverted into a bath of cooler water the can is dramatically crushed by atmosphere pressure?

The rapid cooling of the can causes the water vapor inside to condense, creating a vacuum. The external atmospheric pressure then crushes the can due to the pressure difference between the inside and outside of the can. This demonstrates the powerful force exerted by atmospheric pressure on objects.

Is liquid more condensed than gas?

Yes, liquid is more condensed than gas because the particles in a liquid are closer together compared to a gas where particles are more spread out. This is why liquids have a definite volume, whereas gases take the shape of their container.

What time of day can fog form?

Fog forms when moisture in the air cools, condenses, and reaches its saturation point. Fog normally forms nearest the ground and upward. This vapor cloud can obscure everything, even a hand held in front of your face. In mountainous areas, fog can lay thickly over roadways, leading to numerous accidents.

What type of front forms from cold air move underneath warm air forcing the warm air to rise?

A cold front forms when cold, dense air advances under warmer, less dense air. As the cold air lifts the warm air, it cools and condenses, leading to the formation of clouds and potentially precipitation. Cold fronts are often associated with strong winds and thunderstorms.

The fast dense current of air which flows across the northern hemispher dividing cold arctic air from warmer southern air is called what?

The fast dense current of air is called the jet stream. It flows west to east, dividing cold Arctic air from warmer southern air in the northern hemisphere, influencing weather patterns and the movement of storms.

The legend or scientific beliefs explanation of typhoon?

A typhoon is a tropical storm that occurs in the Northwest Pacific ocean. It is a cyclone that occurs most often between the International date line and the equator. The legend of the typhoon dates back to the Greek Gods when a Typhon was the most feared God in Olympus until Zeus threw 100 lightening bolts at him and knocking him off Mount Olympus.

Relation between Dew point temperature and pressure?

Dew point temperature is the temperature at which air becomes saturated with moisture and dew forms. As pressure increases, the air can hold more moisture before reaching saturation, leading to a higher dew point temperature. Conversely, a decrease in pressure lowers the air's capacity to hold moisture, resulting in a lower dew point temperature.
