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 ...
As these larger water droplets descend, coalescence continues, so that drops become heavy enough to overcome air resistance and fall as rain. [30] Raindrops have sizes ranging from 5.1 to 20 millimetres (0.20 to 0.79 in) mean diameter, above which they tend to break up. Smaller drops are called cloud droplets, and their shape is spherical.
Sleet is also called ice pellets. Freezing rain occurs when the wedge of warm air aloft is much thicker, allowing the raindrop to survive until it comes in contact with the cold ground.
Hailstones generally fall at higher speeds as they grow in size, though complicating factors such as melting, friction with air, wind, and interaction with rain and other hailstones can slow their descent through Earth's atmosphere. Severe weather warnings are issued for hail when the stones reach a damaging size, as it can cause serious damage ...
Natural gas prices are down nearly 40% year to date amid a glut in supply and a milder-than-expected winter.But analysts see an upside for the commodity going into the end of the year — in part ...
Natural gas burning on a gas stove Burning of natural gas coming out of the ground. Natural gas (also called fossil gas, methane gas, or simply gas) is a naturally occurring mixture of gaseous hydrocarbons consisting primarily of methane (95%) [1] in addition to various smaller amounts of other higher alkanes.
Natural gas prices at the Waha Hub in West Texas have been negative a record number of times so far this year. ... when the COVID-19 pandemic turned global markets upside-down and the price of U.S ...
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 ...
