Any food-safe container with a lid that can hold roughly 3 inches of potting mix will do. Winter sowing in upcycled containers creates stronger seedlings in spring
Unlike hail or sleet, graupel is soft and can be crushed easily in your hand, and is sometimes called "soft hail." It is also usually smaller than hail, with a diameter of around 0.08-0.2 inches.
The depth of low-level warm air (below the freezing level) needed to melt snow falling from above to rain varies from about 230–460 m (750–1,500 ft) and depends on the mass of the flakes and the lapse rate of the melting layer. Rain and snow typically mix when the melting layer depth falls between these values as rain starts forming when in ...
Precipitation, especially rain, has a dramatic effect on agriculture. All plants need at least some water to survive, therefore rain (being the most effective means of watering) is important to agriculture. While a regular rain pattern is usually vital to healthy plants, too much or too little rainfall can be harmful, even devastating to crops.
Under some atmospheric conditions, snow crystals may encounter supercooled water droplets. These droplets, which have a diameter of about 10 μm (0.00039 in) on average, can exist in the liquid state at temperatures as low as −40 °C (−40 °F), far below the normal freezing point as long as it is above the homogeneous nucleation point of ...
Snow hydrology is used to estimate the characteristics of snowfall in different topographical regions. This includes information on snow depth, density, composition and possible runoff patterns. It is also widely used in the study of natural phenomena such as: blizzards, avalanche, ice pellets and hail in order to help foresee natural disasters ...
The use of active microwave data to map snow-cover characteristics is limited by the fact that only wet snow can be recognized reliably. The most frequently used methods to map and measure snow extent, snow depth and snow water equivalent employ multiple inputs on the visible–infrared spectrum to deduce the presence and properties of snow.
Heavy, wet snow poses unique challenges and threats in a winter storm: it can cause heart attacks in people shoveling snow, lead to power outages and roof damage, and cause hazardous conditions on ...
