Clockwise motion (abbreviated CW) proceeds in the same direction as a clock's hands relative to the observer: from the top to the right, then down and then to the left, and back up to the top. The opposite sense of rotation or revolution is (in Commonwealth English ) anticlockwise ( ACW ) or (in North American English ) counterclockwise ( CCW ...
Anticyclonic rotation, or anticyclonic circulation, is atmospheric motion in the direction opposite to a cyclonic rotation. For cyclonic rotation, this motion is in a counter-clockwise direction in the Northern Hemisphere and clockwise in the Southern Hemisphere. Thus, just anticyclonic rotation would mean clockwise in the Northern Hemisphere ...
Literally, it means to take a course opposite the apparent motion of the sun viewed from the Northern Hemisphere (the face of this imaginary clock is the ground the viewer stands upon). [1] The earliest recorded use of the word, as cited by the Oxford English Dictionary , is in a 1513 translation of the Aeneid , where it is found in the phrase ...
Cyclonic rotation or cyclonic circulation is the atmospheric motion in the same direction as a planet's rotation, as opposed to anticyclonic rotation.In the case of Earth's rotation, the Coriolis effect causes cyclonic rotation to be in a counterclockwise direction in the Northern Hemisphere and clockwise in the Southern Hemisphere.

The average of the true solar day during the course of an entire year is the mean solar day, which contains 86,400 mean solar seconds. Currently, each of these seconds is slightly longer than an SI second because Earth's mean solar day is now slightly longer than it was during the 19th century due to tidal friction. The average length of the ...
Rotation or rotational motion is the circular movement of an object around a central line, known as an axis of rotation. A plane figure can rotate in either a clockwise or counterclockwise sense around a perpendicular axis intersecting anywhere inside or outside the figure at a center of rotation .
Also amphidrome and tidal node. A geographical location where there is little or no tide, i.e. where the tidal amplitude is zero or nearly zero because the height of sea level does not change appreciably over time (meaning there is no high tide or low tide), and around which a tidal crest circulates once per tidal period (approximately every 12 hours). Tidal amplitude increases, though not ...
Sunwise, sunward or deasil (sometimes spelled deosil), are terms meaning to go clockwise or in the direction of the sun, as seen from the northern hemisphere. The opposite term is widdershins (Lowland Scots), or tuathal (Scottish Gaelic). [1]
