Question: What needs to be removed from a weighing gauge before snowfall occurs?

Answer: funnel

Other types of gauges include the popular wedge gauge (the cheapest rain gauge and most fragile), the tipping bucket rain gauge, and the weighing rain gauge. The wedge and tipping bucket gauges will have problems with snow. Attempts to compensate for snow/ice by warming the tipping bucket meet with limited success, since snow may sublimate if the gauge is kept much above freezing. <hl> Weighing gauges with antifreeze should do fine with snow, but again, the funnel needs to be removed before the event begins. <hl> For those looking to measure rainfall the most inexpensively, a can that is cylindrical with straight sides will act as a rain gauge if left out in the open, but its accuracy will depend on what ruler is used to measure the rain with. Any of the above rain gauges can be made at home, with enough know-how.

Question: What are hydrometeors?

A concept used in precipitation measurement is the hydrometeor.  Bits of liquid or solid water in the atmosphere are known as hydrometeors.  Formations due to condensation, such as clouds, haze, fog, and mist, are composed of hydrometeors.  All precipitation types are made up of hydrometeors by definition, including virga, which is precipitation which evaporates before reaching the ground.  Particles blown from the Earth's surface by wind, such as blowing snow and blowing sea spray, are also hydrometeors.

Question: How many categories of satellite sensors used for precipitation are there?

Satellite sensors now in practical use for precipitation fall into two categories. Thermal infrared (IR) sensors record a channel around 11 micron wavelength and primarily give information about cloud tops. Due to the typical structure of the atmosphere, cloud-top temperatures are approximately inversely related to cloud-top heights, meaning colder clouds almost always occur at higher altitudes. Further, cloud tops with a lot of small-scale variation are likely to be more vigorous than smooth-topped clouds. Various mathematical schemes, or algorithms, use these and other properties to estimate precipitation from the IR data.

Question: What forms when tiny supercooled cloud droplets freeze?

Snow crystals form when tiny supercooled cloud droplets (about 10 μm in diameter) freeze. Once a droplet has frozen, it grows in the supersaturated environment. Because water droplets are more numerous than the ice crystals the crystals are able to grow to hundreds of micrometers in size at the expense of the water droplets.  This process is known as the Wegener–Bergeron–Findeisen process.  The corresponding depletion of water vapour causes the droplets to evaporate, meaning that the ice crystals grow at the droplets' expense.  These large crystals are an efficient source of precipitation, since they fall through the atmosphere due to their mass, and may collide and stick together in clusters, or aggregates.  These aggregates are snowflakes, and are usually the type of ice particle that falls to the ground.  Guinness World Records list the world's largest snowflakes as those of January 1887 at Fort Keogh, Montana; allegedly one measured 38 cm (15 inches) wide. The exact details of the sticking mechanism remain a subject of research.

Snow crystals form when tiny supercooled cloud droplets (about 10 μm in diameter) freeze. Once a droplet has frozen, it grows in the supersaturated environment. Because water droplets are more numerous than the ice crystals the crystals are able to grow to hundreds of micrometers in size at the expense of the water droplets.

Question: What causes the ice crystals to appear white in color?

Although the ice is clear, scattering of light by the crystal facets and hollows/imperfections mean that the crystals often appear white in color due to diffuse reflection of the whole spectrum of light by the small ice particles.  The shape of the snowflake is determined broadly by the temperature and humidity at which it is formed. Rarely, at a temperature of around −2 °C (28 °F), snowflakes can form in threefold symmetry—triangular snowflakes. The most common snow particles are visibly irregular, although near-perfect snowflakes may be more common in pictures because they are more visually appealing.  No two snowflakes are alike, which grow at different rates and in different patterns depending on the changing temperature and humidity within the atmosphere that the snowflake falls through on its way to the ground.  The METAR code for snow is SN, while snow showers are coded SHSN.

Question: When rain happens at intense yet short intervals in scattered locations what is it called?

In meteorology, precipitation is any product of the condensation of atmospheric water vapor that falls under gravity.  The main forms of precipitation include  drizzle, rain, sleet, snow, graupel and hail.  Precipitation occurs when a portion of the atmosphere becomes saturated with water vapor, so that the water condenses and "precipitates".  Thus, fog and mist are not precipitation but suspensions, because the water vapor does not condense sufficiently to precipitate.  Two processes, possibly acting together, can lead to air becoming saturated: cooling the air or adding water vapor to the air. Precipitation forms as smaller droplets coalesce via collision with other rain drops or ice crystals within a cloud.  Short, intense periods of rain in scattered locations are called "showers."

Question: What is responsible for depositing fresh water on the planet?

Precipitation is a major component of the water cycle, and is responsible for depositing the fresh water on the planet. Approximately 505,000 cubic kilometres (121,000 cu mi) of water falls as precipitation each year; 398,000 cubic kilometres (95,000 cu mi) of it over the oceans and 107,000 cubic kilometres (26,000 cu mi) over land. Given the Earth's surface area, that means the globally averaged annual precipitation is 990 millimetres (39 in), but over land it is only 715 millimetres (28.1 in). Climate classification systems such as the Köppen climate classification system use average annual rainfall to help differentiate between differing climate regimes.

Approximately 505,000 cubic kilometres (121,000 cu mi) of water falls as precipitation each year; 398,000 cubic kilometres (95,000 cu mi) of it over the oceans and 107,000 cubic kilometres (26,000 cu mi) over land. <hl> Given the Earth's surface area, that means the globally averaged annual precipitation is 990 millimetres (39 in), but over land it is only 715 millimetres ( 28.1 in ). <hl> Climate classification systems such as the Köppen climate classification system use average annual rainfall to help differentiate between differing climate regimes.

Question: What brings rain to the savannah climes?

Moisture overriding associated with weather fronts is an overall major method of precipitation production.  If enough moisture and upward motion is present, precipitation falls from convective clouds such as cumulonimbus and can organize into narrow rainbands.  Where relatively warm water bodies are present, for example due to water evaporation from lakes, lake-effect snowfall becomes a concern downwind of the warm lakes within the cold cyclonic flow around the backside of extratropical cyclones.  Lake-effect snowfall can be locally heavy.  Thundersnow is possible within a cyclone's comma head and within lake effect precipitation bands.  In mountainous areas, heavy precipitation is possible where upslope flow is maximized within windward sides of the terrain at elevation.  On the leeward side of mountains, desert climates can exist due to the dry air caused by compressional heating.  The movement of the monsoon trough, or intertropical convergence zone, brings rainy seasons to savannah climes.
