What is a underwater ridge?

A mid-ocean ridge or mid-oceanic ridge is an underwater mountain range, formed by plate tectonics. This uplifting of the ocean floor occurs when convection currents rise in the mantle beneath the oceanic crust and create magma where two tectonic plates meet at a divergent boundary.

What is the purpose of Ridge?

Also known as a dry ridge, a ridge roll serves the purpose of keeping moisture from penetrating into the roof from outside. Accordingly, ridge rolls are water-repellent. Moreover, ridge rolls also serve to ensure that air may pass outside so that the roof is ventilated.

How does a ridge look like?

On a map, a ridge is depicted as two contour lines (often of the same contour) running side by side at the same elevation for some distance. When the lines diverge, the ridge is either flattening out to a high plateau or continues to rise with additional contour lines.

What is the difference between a spur and a ridge?

Ridge (Also: Arete or Spur) – A continuous elevated terrain with sloping sides. In the map represented by “U” or “V” shaped contour lines where the higher ground is in the wide opening. Arete is a narrow ridge and a Spur is a smaller ridge branching off a summit or a main ridge.

What is a ridge in weather?

Ridges and troughs are often mentioned on the weather forecast. A ridge is an elongated area of relatively high pressure extending from the center of a high-pressure region. A trough is an elongated area of relatively low pressure extending from the center of a region of low pressure.

How do you read a Metar?

The first two digits are the date, the 16th of the month, and the last four digits are the time of the METAR, which is always given in coordinated universal time (UTC), otherwise known as Zulu time. A “Z” is appended to the end of the time to denote that the time is given in Zulu time (UTC) as opposed to local time.

What does a ridge of high pressure mean?

A ridge is an area of high pressure that does not have a closed circulation; it either extends from a high-pressure area or is sandwiched between a couple of lows. More often than not, a ridge of high pressure divides two low-pressure areas.

What weather is associated with high pressure?

Low-pressure systems are associated with clouds and precipitation that minimize temperature changes throughout the day, whereas high-pressure systems normally associate with dry weather and mostly clear skies with larger diurnal temperature changes due to greater radiation at night and greater sunshine during the day.

What is a trough in aviation?

A trough is an elongated region of relatively low atmospheric pressure without a closed isobaric contour that would define it as a low pressure area. ... Upper-level troughs in the jet stream (as shown in diagram) reflect cyclonic filaments of vorticity.

What is a trough in electrical?

Wireways are designed to protect cables from environmental contaminants such as dust, dirt, oil, and moisture. Wireways—sometimes known as "troughs" or "gutters" within the electrical contracting field—are commonly used to control wiring in environments where contaminants may cause problems.

What is a trough in physics?

Trough – the lowest point below the rest position. Amplitude – the maximum displacement of a point of a wave from its rest position. Wavelength – distance covered by a full cycle of the wave. Usually measured from peak to peak, or trough to trough.

What is a weather depiction chart?

Weather depiction charts show a modified station model that provides sky conditions in the form of total sky cover, ceiling height, weather, and obstructions to visibility, but does not include winds or pressure readings like the surface analysis chart.

How do you read a TAF?

The date and time are formatted using two sets of four digits each with the first two digits representing the day of the month and the second two the 24-hour time in hours only (no minutes since TAFS are issued on the hour). The first set of digits is the start date/time and the second is the end date/time.

What color is a cold front?

On colored weather maps, a cold front is drawn with a solid blue line. There is typically a noticeable temperature change from one side of a cold front to the other.

How do you identify a cold front?

On a weather map, a cold front is usually drawn using a solid blue line with triangles pointing in the direction of the warm air that will be replaced. Cold fronts typically move from northwest to southeast. A cold front can bring cold temperatures, torrential rains and high wind speeds.

What is the symbol of a cold front?

The weather map symbol for a cold front is a blue curved line with blue triangles. The triangles point in the direction the cold air is moving.

What are characteristics of a cold front?

Cold Fronts moisture content (dew point) changes dramatically. wind shift (direction and speed) pressure trough (pressure tendency is useful!!!) often cloudy/showers/thunderstorms/sometimes severe.

Why is it called a cold front?

Temperature changes Cold fronts are the leading edge of cooler air masses, hence the name "cold front". ... The air behind the front is cooler than the air it is replacing and the warm air is forced to rise, so it cools.

What is a frontal passage?

(Acronym fropa.) The passage of a front over a point on the earth's surface; or, the transit of an aircraft through a frontal zone.

What are the first signs of a warm front?

The first signs of an approaching warm front include a general movement of air from southwest to northeast, a drop in air pressure, and warmer air found behind the movement of the front. Warm fronts tend to signal a general change in weather.
