sunrise - 1. The phenomenon of the sun's daily appearance on the eastern horizon as a result of the earth's rotation. Under normal conditions the upper limb of the sun appears to be on the horizon of an observer at sea level.

Sunrise - The time the sun appears above the horizon.
Sunset - The time the sun disappears below the horizon.

DaySunrise to sunset. Day of the week (eg. Monday)Midnight to midnight.Debris cloudA rotating "cloud" of dust or debris, near or on the ground, often appearing beneath a condensation funnel and surrounding the base of a tornado.

Stable CorePost-sunrise, elevated remnant of the temperature inversion that has built up overnight within a valley.

Because the immediate surface (lower Boundary Layer) cools much more rapidly during these conditions than the air just above (upper Boundary Layer), a temperature inversion can be created overnight, but typically erodes quickly after sunrise.

temperature, precipitation, wind, sunrise and sunset times, etc.).Daily Flood PeakIn hydrologic terms, the maximum mean daily discharge occuring in a stream during a given flood event.

SUNRISE The daily appearance of the sun on the eastern horizon as a result of the earth's rotation. In the United States, it is considered as that instant when the upper edge of the sun appears on the sea level horizon.

Humidity RecoveryThe change in relative humidity over a given period of time; generally between late evening and sunrise. The moisture change in the fine fuels during this period is directly related to the amount of humidity recovery.

The lowest (minimum) temperature usually occurs a little while after sunrise, and the highest (maximum) temperature usually occurs after midday --- sometimes as late as 3 or 4 hours after midday.

alpenglow"The occasional reappearance of sunset colors on a (snow-covered) mountaintop soon after sunset and a similar phenomenon before sunrise. Alpenglow has three phases.

Red, orange, and pink clouds occur almost entirely at sunrise/sunset, and are the result of the scattering of sunlight by the atmosphere itself.

Civil Twilight - The period of time before sunrise and after sunset when the sun is not more than 6° below the horizon.
Nautical Twilight - The period of time before sunrise and after sunset when the sun is not more than 12° below the horizon.

Typically seen during sunrise or sunset, sun pillars form when sunlight reflects off the surfaces of ice crystals associated with thin, high-level clouds (e.g.cirrostratus clouds).

Generally, the period between late evening and sunrise. Windy or cloudy conditions will tend to produce slow temperature recovery, while clear, calm weather can cause rapid recovery.

Fog usually disperses soon after sunrise, as the Sun's rays gradually warm the ground. Because clear skies are required for radiation fog to occur, a fine day normally follows.

Why is the sky a red-orange colour at sunset and sunrise?
At sunrise and sunset, sunlight passes through far more air before reaching us.

Duration of the period from sunrise to sunset.
dBZ
Nondimensional "unit" of radar reflectivity which represents a logarithmic power ratio (in decibels, or dB) with respect to radar reflectivity factor, Z.

DAWN The first appearance of light in the eastern sky before sunrise. It marks the beginning of morning twilight.

Day length: duration of the period from sunrise to sunset.
Dew-point (dew point temperature): the temperature to which air must be cooled (at constant pressure and constant water vapor content) for saturation to occur.

A sun pillar is a vertical shaft of light extending upward or downward from the sun. Typically seen during sunrise or sunset, sun pillars form when sunlight reflects off the surfaces of falling ice crystals associated with thin, ...

twilight—The intervals of incomplete darkness following sunset and preceding sunrise.

Twilight
An intermediate period of illumination of the sky before sunrise and after sunset; there are three definitions of twilight: civil, nautical, and astronomical.
Typhoon
Maximum wind speed of 64 knots or more.

Twilight The time immediately before sunrise and after sunset when the sky remain illuminated.
Typhoon A hurricane that forms in the western Pacific Ocean.
U ...

Noctilucent clouds Wavy, thin clouds resembling cirrus, but usually bluish-white or silvery; best seen at high latitudes just before sunrise or just after sunset.

I smell the new rain, feel the sun on my back and wind in my hair (what little is left), taste new fallen snow, see the glorious colours and textures of sunrise and sunset, hear the thunder rumble in the distance.

Sun Pillar - a luminous streak of white or slightly reddened light extending vertically above and below the sun, most frequently observed near sunrise or sunset ...

In simple terms twilight is the term used to describe the period of incomplete darkness that occurs after sunset and before sunrise. It is derived from Saxon or Middle English terms, which imply that it occurs twice daily.

data in this report are presented in a tabular form; however, some narrative statements may also be used in the product. The report is organized so that similar items are grouped together (i.e., temperature, precipitation, wind, sunrise and sunset ...
