Winter brings less daylight and colder temperatures, which can disrupt sleep. Seasonal Affective Disorder (SAD) is more common in winter due to the lack of sunlight, causing sleep disturbances.
Precipitation is measured using a rain gauge, and more recently remote sensing techniques such as a weather radar. When classified according to the rate of precipitation, rain can be divided into categories. Light rain describes rainfall which falls at a rate of between a trace and 2.5 millimetres (0.098 in) per hour. Moderate rain describes ...
A virga, also called a dry storm, is an observable streak or shaft of precipitation that evaporates or sublimates before reaching the ground. [1] A shaft of precipitation that does not evaporate before reaching the ground is known in meteorology as a precipitation shaft.
A winter fog for rain. A fact most everywhere, In valley or on plain. Fog is formed when the air cools enough that the vapour pressure encourages condensation over evaporation. In order for the air to be cool on a summer night, the sky must be clear, so excess heat can be radiated into space. Cloudy skies act like a blanket, absorbing and ...
The Kona coast is the only area in Hawaii with a summer precipitation maximum. Windward sides face the east to northeast trade winds and receive much more rainfall; leeward sides are drier and sunnier, with less rain and less cloud cover. [69] In the late winter and spring during El Niño events, drier than average conditions can be expected in ...
“In this case, by the time we get another weather system, the cold air will have moderated, or warmed up, and any precipitation will be rain. And that wouldn’t be until late next week,” he said.
In winter, an inversion can lead to the development of ice pellets and freezing rain. Both these phenomena occur when snow melts in a warm layer aloft and falls into a colder layer near the surface. If the layer of cold air near the surface is thick enough, it will lead to the development of ice pellets as the raindrops re-freeze.
Winter storm watch WSA – Hazardous winter weather conditions including significant accumulations of snow and/or freezing rain and/or sleet are possible generally within 24 to 48 hours. The generic term, Winter Storm Watch, is used for hazardous winter precipitation in the form of heavy snow, freezing rain or sleet, or a combination of the ...
