  2. Rain sensor - Wikipedia

    en.wikipedia.org/wiki/Rain_sensor

    Rain sensor on the windshield of a car. A rain sensor or rain switch is a switching device activated by rainfall. There are two main applications for rain sensors. The first is a water conservation device connected to an automatic irrigation system that causes the system to shut down in the event of rainfall.

  3. Residual-current device - Wikipedia

    en.wikipedia.org/wiki/Residual-current_device

    A residual-current device (RCD), residual-current circuit breaker (RCCB) or ground fault circuit interrupter (GFCI) [a] is an electrical safety device, more specifically a form of Earth-leakage circuit breaker, that interrupts an electrical circuit when the current passing through line and neutral conductors of a circuit is not equal (the term residual relating to the imbalance), therefore ...

  4. Wegener–Bergeron–Findeisen process - Wikipedia

    en.wikipedia.org/wiki/Wegener–Bergeron...

    The Wegener–Bergeron–Findeisen process (after Alfred Wegener, Tor Bergeron and Walter Findeisen []), (or "cold-rain process") is a process of ice crystal growth that occurs in mixed phase clouds (containing a mixture of supercooled water and ice) in regions where the ambient vapor pressure falls between the saturation vapor pressure over water and the lower saturation vapor pressure over ice.

  5. Surface runoff - Wikipedia

    en.wikipedia.org/wiki/Surface_runoff

    Surface runoff can cause erosion of the Earth's surface; eroded material may be deposited a considerable distance away. There are four main types of soil erosion by water: splash erosion, sheet erosion, rill erosion and gully erosion. Splash erosion is the result of mechanical collision of raindrops with the soil surface: soil particles which ...

  6. Rain-X - Wikipedia

    en.wikipedia.org/wiki/Rain-X

    The primary use of Rain-X is for automotive applications. Commercially sold "Original Glass Treatment" is the original and most well known Rain-X branded product. It is a hydrophobic silicone polymer [3] that forces water to bead and roll off of the car, often without needing wipers. It is sold in bottles of 3.5 or 7 US fluid ounces (100 or 210 ...

  7. Precipitation - Wikipedia

    en.wikipedia.org/wiki/Precipitation

    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.

  8. First flush - Wikipedia

    en.wikipedia.org/wiki/First_flush

    The term "first flush effect" refers to rapid changes in water quality (pollutant concentration or load) that occur after early season rains. Soil and vegetation particles wash into streams; sediments and other accumulated organic particles on the river bed are re-suspended, and dissolved substances from soil and shallow groundwater can be flushed into streams.

  9. Fishtailing - Wikipedia

    en.wikipedia.org/wiki/Fishtailing

    Diagram of a car undergoing fishtailing. Video of a car fishtailing or drifting on the street of Riia maantee in Tartu, Estonia (December 2021) Fishtailing is a vehicle handling problem which occurs when the rear wheels lose traction, resulting in oversteer. This can be caused by low-friction surfaces (sand, gravel, rain, snow, ice, etc.).
