ETYM Old Eng. sesoun, French saison, properly, the sowing time, from Latin satio a sowing, a planting, from serere, satum, to sow, plant; akin to Eng. sow, v., to scatter, as seed.
1. A period of the year marked by special events or activities in some field; or.
2. A recurrent time marked by major holidays.
3. One of the natural periods into which the year is divided by the equinoxes and solstices or atmospheric conditions; SYN. time of year.
Period of the year having a characteristic climate. The change in seasons is mainly due to the change in attitude of the Earth's axis in relation to the Sun, and hence the position of the Sun in the sky at a particular place. In temperate latitudes four seasons are recognized: spring, summer, autumn (fall), and winter. Tropical regions have two seasons—the wet and the dry. Monsoon areas around the Indian Ocean have three seasons: the cold, the hot, and the rainy.
The northern temperate latitudes have summer when the southern temperate latitudes have winter, and vice versa. During winter, the Sun is low in the sky and has less heating effect because of the oblique angle of incidence and because the sunlight has further to travel through the atmosphere. The differences between the seasons are more marked inland than near the coast, where the sea has a moderating effect on temperatures. In polar regions the change between summer and winter is abrupt; spring and autumn are hardly perceivable. In tropical regions, the belt of rain associated with the trade winds moves north and south with the Sun, as do the dry conditions associated with the belts of high pressure near the tropics. The monsoon's three seasons result from the influence of the Indian Ocean on the surrounding land mass of Asia in that area.
A verbal formula believed to have magical force; SYN. magic spell, charm.
Sinonimi: lunar time period
ETYM as. tîd time.
1. Something that may increase or decrease (like the tides of the sea).
2. The periodic rise and fall of the sea level under the gravitational pull of the moon.
3. There are usually two high and two low tides each day; SYN. lunar time period.
The rhythmic rise and fall of sea level in Earth's oceans and their inlets and estuaries due to the gravitational attraction of the Moon and, to a lesser extent, the Sun, affecting regions of Earth unequally as it rotates. Water on the side of Earth nearest the Moon feels the Moon's pull and accumulates directly below it producing high tide.
High tide occurs at an interval of 12 hr 24 min 30 sec. The maximum high tides, or spring tides, occur at or near new and full Moon when the Moon and Sun are in line and exert the greatest combined gravitational pull. Lower high tides, or neap tides, occur when the Moon is in its first or third quarter and the Moon and Sun are at right angles to each other.
ETYM Old Eng. time, as. tîma, akin to tîd time, and to Icel. tîmi, Dan. time an hour, Swed. timme. Related to Tide.
Continuous passage of existence, recorded by division into hours, minutes, and seconds. Formerly the measurement of time was based on the Earth's rotation on its axis, but this was found to be irregular. Therefore the second, the standard si unit of time, was redefined 1956 in terms of the Earth's annual orbit of the Sun, and 1967 in terms of a radiation pattern of the element cesium.
Universal time (ut), based on the Earth's actual rotation, was replaced by coordinated universal time (utc) 1972, the difference between the two involving the addition (or subtraction) of leap seconds on the last day of June or Dec. National observatories make standard time available in various countries. From 1986 the term Greenwich Mean Time was replaced by utc. However, the Greenwich meridian, adopted 1884, remains that from which all longitudes are measured, and the world's standard time zones are calculated from it.
1. The continuum of experience in which events pass from the future through the present to the past.
2. An indefinite period (usually marked by specific attributes or activities).
3. An instance or single occasion for some event; SYN. clip.
4. A suitable moment.
5. A person's experience on a particular occasion; or.
6. A duration considered as a resource under one's control and sufficient to accomplish something.
1. The act of changing or reversing the direction of the course; SYN. turning.
2. Turning away or in the opposite direction.
3. The activity of doing something in an agreed succession; or; SYN. play.
4. An unforeseen development; SYN. turn of events, twist.
5. A favor for someone; SYN. good turn.

7. (In sports) A period of play during which one team is on the offensive; SYN. bout, round.
ETYM Old Eng. weder, AS. weder.
(Homonym: wether, whether).
The meteorological conditions: temperature and wind and clouds and precipitation; SYN. weather condition, atmospheric condition.
Day-to-day variation of climatic and atmospheric conditions at any one place, or the state of these conditions at a place at any one time. Such conditions include humidity, precipitation, temperature, cloud cover, visibility, and wind. To a meteorologist the term “weather” is limited to the state of the sky, precipitation, and visibility as affected by fog or mist. A region’s climate is derived from the average weather conditions over a long period of time. See also meteorology.
Weather forecasts, in which the likely weather is predicted for a particular area, based on meteorological readings, may be short-range (covering a period of one or two days), medium-range (five to seven days), or long-range (a month or so). Readings from a series of scattered recording stations are collected and compiled on a weather map. Such a procedure is called synoptic forecasting. The weather map uses conventional symbols to show the state of the sky, the wind speed and direction, the kind of precipitation, and other details at each gathering station. Points of equal atmospheric pressure are joined by lines called isobars. The trends shown on such a map can be extrapolated to predict what weather is coming.
