They indicate a large pressure difference over a small area, which will cause strong winds.
Light winds
cumulus
Wind vane
An anticyclone, also known as a 'high' can be identified on a weather chart as an often large area of widely spaced isobars, where pressure is higher than surrounding areas. In the Northern Hemisphere winds blow in a clockwise direction around high pressure. The highest pressure occurs at the centre and is known as the 'high pressure centre'. Anticyclones can bring warm and sunny weather in summer, but cold and foggy weather in winter.A depression, also known as a 'low' can be recognised on a weather chart by an area of closely spaced isobars, often in a roughly circular shape, where pressure is lower than surrounding areas. They are often accompanied by fronts. In the Northern Hemisphere winds blow around depressions in an anticlockwise direction. The lowest pressure occurs at the middle of a depression, this is known as the 'low pressure centre'. Depressions are often associated with strong winds and heavy rain and are nearly always accompanied by fronts.Troughs Troughs are elongated extensions of areas of low pressure. They bring similar weather to that associated with depressions. Ridges Ridges are elongated extensions of areas of high pressure. They bring similar weather to that associated with anticyclones. Col A col can be identified as an area of slack pressure between two anticyclones and two depressions. The following diagram summarises the appearance on a weather chart of the main types of pressure systems. Cold fronts and warm fronts Cold fronts can be identified on weather charts as bold lines with triangles. These are blue when displayed on colour charts. The points of the triangle indicate the direction in which the front is moving. A cold front indicates a change in air mass, where warmer air is being replaced by colder air. They often bring short spells of heavy rainfall in the form of showers and squally winds, and are accompanied by a decrease in temperature, a veer in wind direction and a change to brighter showery conditions. Warm fronts can be identified on weather charts as bold lines with semi-circles or humps. These are coloured red when displayed on colour charts. The direction of the humps indicates the direction in which the front is moving. A warm front indicates a change from a colder to a warmer air mass. They often bring spells of prolonged and sometimes heavy rainfall, with strong winds. Occluded fronts Occluded fronts can be identified on weather charts as bold lines with sets of triangles and semi-circles. These are coloured purple on coloured weather charts. The direction in which the symbols face indicates the direction in which the front is travelling. Occlusions are formed when the cold front overtakes the warm front, therefore they have similar characteristics to a cold front, but less intense. Warm Sector The warm sector of a depression is located behind the warm front and ahead of the cold front. It often brings mild temperatures but the weather can be overcast with drizzle.
Depends on which lines you're talking about. If you're talking about circles that cover the map (often in black or gray) then those are isobars which are lines of equal pressure (ie. the barometer reads the same everywhere along a line)....If you're talking about a blue line with triangles, that means a cold front with cooler/drier air behind it. A red line with round barbs means a warm front with warmer air behind it. There are many others, but these are the most common seen on television weather forecasts.
It basically means the same thing. In science, "theory" is often used for well-established relationships; while "hypothesis" is used for guesswork that still needs further confirmation before it is widely accepted.
'To be spaced' might refer to 'being spaced out'. Which often means someone is high from a kind of substance abuse, or just in a total state of confusion.
"Grin" is a facial expression where a person smiles widely, often showing their teeth. It can indicate happiness, amusement, or satisfaction.
Those most often seen on weather charts are isobars. These connect areas of equal atmospheric pressure.
Goosebumps or goose skin is an old name for human skin when the thinly spaced hairs on the arm stand up, usually when it is cold or someone is startled. The widely spaced bumps in the skin look very similar to the skin of a goose (or any poultry, but geese were commonly eaten by the peasant class and therefore seen more often) that has been killed and had the feathers plucked off.
The names of muscles often indicate the action of the muscle. What does the term levator mean?
true
cumulus
Nail issues can often indicate a vitamin deficiency. White spots indicate a lack of Calcium, small vertical ridges indicate a lack of Potassium.
When the smoke detector first starts signaling low battery with short widely spaced high pitched chirps, or if when you press the test button the alarm does not trigger.After replacing the batteries, press the test button. If the alarm does not trigger with fresh batteries, replace the smoke detector.
A ratio can indicate division. If you have a ratio, x:y, then it can be thought of as x/y.
They're not evenly spaced ... there can be none in a year, or as many as five. The average during the entire 20th Century was 2.29 per year.
The word term paper is often related to college students and a paper that is written at the end of each term that is worth a fraction of their final grade for said class. It is usually required to have a certain about of words and/or pages and typed either single spaced or double spaced.
