A 120° parhelion is a type of atmospheric optical phenomenon that occurs when sunlight interacts with ice crystals in the atmosphere, particularly in cirrus or cirrostratus clouds. It is a specific form of parhelion, also known colloquially as "sun dogs.

Atmospheric ghost lights, often referred to as "ghost lights" or "will-o'-the-wisps," are mysterious lights seen in certain geographical areas, typically at night or in low-light conditions. These lights can appear as glowing orbs, flickering flames, or steady points of light and are often associated with rural or marshy environments. The phenomenon has a rich history in folklore, with various cultures attributing the light to spirits, fairies, or other supernatural entities.

Zonal wavenumber is a term used in atmospheric science and oceanography to describe the spatial frequency of wave patterns in a zonal (east-west) direction in a periodic system, like the Earth's atmosphere or ocean. It quantifies how many wavelengths fit into a given distance in the zonal direction.

As of my last knowledge update in October 2023, "Wave Cloud" might refer to a few different concepts depending on the context, and it could be related to various fields such as technology, cloud computing, or environmental studies. Here are a couple of possible interpretations: 1. **Wave Cloud in Computing:** In the context of cloud computing, "Wave Cloud" might refer to a platform or service that offers cloud-based solutions for processing or managing data in ways that resemble wave patterns.

The Von Kármán wind turbulence model is a mathematical representation used to describe the characteristics and behavior of atmospheric turbulence, particularly in the context of wind speed and wind direction variability. Named after the Hungarian-American engineer Theodore von Kármán, this model is particularly pertinent in fields such as meteorology, aerospace engineering, and environmental studies.

An undular bore is a type of wave phenomenon typically observed in shallow water bodies, such as rivers or estuaries, where a sudden change in flow conditions leads to the formation of waves. This phenomenon is characterized by a series of oscillations or undulations that occur as a result of the interaction between a flowing fluid and a sudden change in water depth, velocity, or other conditions, such as the inflow of water from rainfall or upstream sources.

The tropical rain belt, often referred to as the Intertropical Convergence Zone (ITCZ), is a region near the equator where the trade winds of the northern and southern hemispheres come together. This convergence leads to significant rising air, which contributes to the formation of clouds and precipitation.

Trade winds are steady, recurring winds that predominantly blow from east to west in the tropics and subtropics, between approximately 30 degrees north and 30 degrees south latitude. These winds are primarily produced by the Earth’s rotation and the differential heating of the Earth’s surface by the sun. The trade winds are part of the larger global wind system and are crucial for maritime navigation, as they historically guided sailing ships across the oceans.

Topographic steering typically refers to a concept in meteorology and atmospheric science where the topography of the Earth, such as mountains, valleys, and other landforms, influences the movement and behavior of atmospheric phenomena, such as air masses, wind patterns, and precipitation. In the context of meteorology: 1. **Wind Patterns**: Topography can alter wind flow by channeling, blocking, or redirecting air currents.

Thermal wind is a concept in meteorology that refers to the change in wind speed and direction that is associated with differences in temperature between air masses. It is not a physical wind in the sense of a local wind like a sea breeze or mountain breeze but rather a theoretical concept used to describe the influence of thermal gradients on the wind pattern in the atmosphere.

The Somali Jet, also known as the Somali Jet Stream, refers to a low-level jet stream that occurs over the Horn of Africa, particularly affecting Somalia and surrounding regions. This phenomenon typically arises during the southwest monsoon season, which generally occurs from June to September. The Somali Jet is characterized by strong winds that transport moisture and can influence weather patterns across the region.

Synoptic scale meteorology refers to the study of weather systems and phenomena that cover large geographic areas, typically ranging from about 100 kilometers (62 miles) to several thousand kilometers (thousands of miles) in size. This scale of meteorology primarily focuses on the atmospheric processes and patterns associated with high-pressure and low-pressure systems, fronts, and other large-scale weather features.

Sudestada is a meteorological phenomenon that occurs in the southeastern part of South America, particularly affecting areas such as Argentina, Uruguay, and parts of Brazil. It is characterized by sustained winds from the southeast, which can bring significant weather changes, including increased humidity, cloud cover, and precipitation. During a Sudestada, moist air from the Atlantic Ocean is forced inland, often resulting in heavy rainfall, thunderstorms, and the potential for flooding, particularly in low-lying areas.

Sudden stratospheric warming (SSW) refers to a rapid increase in temperature in the stratosphere, particularly over the polar regions, that can occur in winter. This phenomenon typically involves a significant change in the dynamics of the atmosphere, primarily affecting the polar vortex, which is a large area of low pressure and cold air surrounding the Earth’s poles.

Stratified flows refer to a type of fluid flow where different layers, or strata, of fluids with varying densities or compositions exist and move relative to each other. This phenomenon is commonly observed in various natural and industrial processes, such as in lakes, oceans, and oil reservoirs, as well as in pipelines where fluids of different densities are transported. Key characteristics of stratified flows include: 1. **Density Differentiation**: The fluids involved have distinct densities, leading to the formation of layers.

The South Atlantic Convergence Zone (SACZ) is a meteorological feature found in the South Atlantic Ocean, characterized by a region where moist air converges. It is a significant zone for weather patterns, particularly in Southern Brazil and surrounding areas. ### Key Features of SACZ: 1. **Formation**: The SACZ is formed by the convergence of trade winds coming from the Atlantic Ocean, which interact with the tropical and subtropical air masses.

In meteorology, a solenoid refers to a conceptual model used to explain certain motion or flow patterns in the atmosphere, particularly related to the dynamics of the atmosphere and ocean interactions. Solenoids can help describe the behavior of fluid flow, including aspects like vortices and turbulence. However, it's important to note that the term "solenoid" is more commonly associated with electromagnetism as a type of coil that generates a magnetic field when an electric current passes through it.

Secondary organic aerosol (SOA) refers to fine particles (aerosols) that form in the atmosphere from the gas-phase oxidation of organic compounds. These organic compounds, which can originate from both anthropogenic (human-made) and biogenic (natural) sources, undergo chemical reactions when they react with oxidizing agents, such as hydroxyl radicals (•OH) or ozone (O3).

Scale height is a concept used in atmospheric science and astrophysics to describe the rate at which the pressure or density of an atmosphere decreases with altitude (or distance from the center of a celestial body).

The Rossby radius of deformation is a fundamental characteristic scale in geophysical fluid dynamics, particularly in oceanography and meteorology. It represents the horizontal distance over which a wave (like a gravity wave) can propagate in a rotating fluid, such as the Earth's atmosphere or oceans, before being significantly affected by the rotational Coriolis force.
