Which of the following clouds is most closely associated with precipitation?
Cumulus clouds are created by strong updrafts of warm, moist air. Most forms of heavy precipitation fall from cumulus clouds.
How do we describe air that resists vertical movement?
The atmosphere is said to be stable when the air parcels within the atmosphere resist all vertical movement. Stable air has a negative buoyancy.
Is the land on the leeward side of a mountain range is in a rain shadow?
A rain shadow is an area of significantly reduced rainfall behind a mountainous region, on the side facing away from prevailing winds, known as its leeward side.
What is the climate on the leeward side of a mountain differs?
In contrast to the moist windward side of a mountain, the leeward side typically has a dry, warm climate. This is because by the time air rises up the windward side and reaches the summit, it has already been stripped of the majority of its moisture.
Which form of precipitation turns into ice the instant it collects with a solid object?
Warm Rain Process Supercooled raindrops develop as microscopic cloud droplets collect one another as they fall. Ice processes are not involved in the formation of these raindrops. The precipitation falls to the surface as supercooled rain or drizzle and freezes instantly on contact.
What are the main types of atmospheric lifting and precipitation?
– There are four lifting mechanisms that form clouds: Orographic Lifting, Convection, Convergence, and Updraft. – Orographic lifting is when air cannot go through a mountain, and so it flows over it. – Frontal Lifting is when less dense warm air is forced to rise over cooler, denser air as a weather fronts move.
Which of the following weather phenomena leads to cloud formation precipitation?
Clouds are formed when air containing water vapor is cooled below a critical temperature called the dew point and the resulting moisture condenses into droplets on microscopic dust particles (condensation nuclei) in the atmosphere. The air is normally cooled by expansion during its upward movement.
Which precipitation type is caused by a cloud with temperatures below freezing from the ground all the way to the top of the cloud?
Freezing rain is liquid (supercooled) that will freeze on contact with objects that are below freezing on the surface.
How does atmospheric stability influence the upward and downward motions of air parcels?
In a stable atmosphere, vertical motion is suppressed and a displaced parcel will move back toward its original position. On the other hand, in an unstable atmosphere air parcels displaced either upward or downward will continue in that direction.
What is vertical temperature explain vertical stability of atmosphere?
The vertical temperature profile of the atmosphere changes as different air masses dominate a region. If the temperature profile is known, the rate of change of temperature with height (the environmental lapse rate), and thus the stability of the atmosphere, at that point in time can be determined.
What is the term that applies to the leeward slope of a mountain and beyond?
Precipitation caused by the lifting of air over mountain ranges is called: rain shadow. A belt of dry climate that extends down the leeward slope of mountains and beyond is called: convection.
What is the leeward side of a mountain?
The leeward—or "lee"—side is the one sheltered from the wind by the reference point. Windward and leeward aren't frivolous terms. When applied to mountains, they are important factors in weather and climate—one is responsible for enhancing precipitation in the vicinity of mountain ranges, while the other withholds it.
What is the leeward side of a mountain called?
The leeward—or "lee"—side is the one sheltered from the wind by the reference point. Windward and leeward aren't frivolous terms. When applied to mountains, they are important factors in weather and climate—one is responsible for enhancing precipitation in the vicinity of mountain ranges, while the other withholds it.
What is precipitation name the different types of precipitation?
The most common types of precipitation are rain, hail, and snow. Rain is precipitation that falls to the surface of the Earth as water droplets. Raindrops form around microscopic cloud condensation nuclei, such as a particle of dust or a molecule of pollution.
What is called precipitation?
Precipitation is water released from clouds in the form of rain, freezing rain, sleet, snow, or hail. It is the primary connection in the water cycle that provides for the delivery of atmospheric water to the Earth. Most precipitation falls as rain.
When air that is forced to rise over an obstruction such as a mountain it is called?
– Orographic lifting is when air cannot go through a mountain, and so it flows over it. – Frontal Lifting is when less dense warm air is forced to rise over cooler, denser air as a weather fronts move.
Where does Convectional lifting occur?
Convective lifting is air lifting by convection. Convection occurs in all fluids, and is the process of warm particles rising and cool particles sinking. Convection is most likely to occur in 'hot spots' on Earth's surface because these areas get warmed more than others.
What is the process by which precipitation forms in a cloud that has a temperature that is above freezing?
supercooled warm-rain process Warm Rain Process A less common way that freezing rain forms is through supercooled warm-rain process (SWRP), where cloud top temperatures are warmer than about -10°C. Supercooled raindrops develop as microscopic cloud droplets collect one another as they fall.
Which process forms clouds and precipitation?
Clouds are condensed droplets or ice crystals from atmospheric water vapor. Clouds form by the rising and cooling of air caused by convection, topography, convergence, and frontal lifting.
Which type of precipitation is water vapor that condenses into ice crystals in clouds?
Snow is precipitation in the form of ice crystals. It originates in clouds when temperatures are below the freezing point (0 degrees Celsius, or 32 degrees Fahrenheit), when water vapor in the atmosphere condenses directly into ice without going through the liquid stage.
What is the atmospheric stability condition of environmental lapse rate is greater than adiabatic lapse rate?
The atmosphere is said to be absolutely unstable if the environmental lapse rate is greater than the dry adiabatic lapse rate. This means that a rising air parcel will always cool at a slower rate than the environment, even when it is unsaturated.
What is atmospheric stability and temperature inversion?
The atmosphere is usually most stable early in the morning. A temperature inversion represents an extremely stable situation. Rising parcels always cool with increasing altitude (at either the dry or moist rate). In an inversion the surrounding air gets warmer and warmer with altitude.
What is the term that applies to the leeward slope of a mountain and beyond quizlet?
Precipitation caused by the lifting of air over mountain ranges is called: rain shadow. A belt of dry climate that extends down the leeward slope of mountains and beyond is called: convection.
What is a leeward slope?
The term leeward, or lee, refers to slopes that are oriented away from the wind. If winds are strong enough, snow from windward slopes can be redistributed or blown to leeward areas, causing them to become loaded. Wind slabs often form on lee aspects as a result of this wind transport. See also: Wind Effect.
What is windward precipitation?
Once the damp air makes landfall on an island, it ascends hills and mountains to form condensation, clouds, and precipitation. As the air moves to the other side of the island, it warms up and dries out. Thus, an island's windward side is wetter and more verdant than its drier leeward side.
What are the four types of precipitation?
There are many different types of precipitation —rain, snow, hail, and sleet for example—yet they all have a few things in common. They all come from clouds. They are all forms of water that fall from the sky.
What are types of precipitation?
The different types of precipitation are:
- Rain. Most commonly observed, drops larger than drizzle (0.02 inch / 0.5 mm or more) are considered rain. …
- Drizzle. Fairly uniform precipitation composed exclusively of fine drops very close together. …
- Ice Pellets (Sleet) …
- Hail. …
- Small Hail (Snow Pellets) …
- Snow. …
- Snow Grains. …
- Ice Crystals.
What is called orographic rainfall?
orographic precipitation, rain, snow, or other precipitation produced when moist air is lifted as it moves over a mountain range. As the air rises and cools, orographic clouds form and serve as the source of the precipitation, most of which falls upwind of the mountain ridge.
