Acid rain is rain or any other form of precipitation that is unusually acidic, meaning that it has elevated levels of hydrogen ions (low pH).Most water, including drinking water, has a neutral pH that exists between 6.5 and 8.5, but acid rain has a pH level lower than this and ranges from 4–5 on average.
Diagram depicting the sources and cycles of acid rain precipitation. Freshwater acidification occurs when acidic inputs enter a body of fresh water through the weathering of rocks, invasion of acidifying gas (e.g. carbon dioxide), or by the reduction of acid anions, like sulfate and nitrate within a lake, pond, or reservoir.

Rainfall: Average rainfall has a pH of 5.6 and is moderately acidic due to dissolved atmospheric carbon dioxide (CO 2) that combines with water to form carbonic acid (H 2 CO 3). When this water flows through the soil it results in the leaching of basic cations as bicarbonates; this increases the percentage of Al 3+ and H + relative to other ...
This compound causes rainfall pH to be around 5.0–5.5. When rainfall has a lower pH than natural levels, it can cause rapid acidification of soil. Sulfur dioxide and nitrogen oxides are precursors of stronger acids that can lead to acid rain production when they react with water in the atmosphere
Rainfall in these regions averages between 300 and 600 millimeters (11.8 and 23.6 in) per year, with lower amounts across Baja California Norte. Average rainfall totals are between 600 and 1,000 millimeters (23.6 and 39.4 in) in most of the major populated areas of the southern altiplano, including Mexico City and Guadalajara.
Projected rainfall levels could change, especially with any potential tropical storm activity as hurricane season wares on, Coniglio said. This article originally appeared on Cincinnati Enquirer: ...
Governor declares State of Emergency. Friday 29 September 2023 15:26, Oliver O'Connell. New York Governor Kathy Hochul has declared a state of emergency due to the extreme rainfall.
Low level cold in the winter sweeping in from Canada combine with relatively warmer, unfrozen lakes to produce dramatic lake-effect snow on the eastern and southern shores of the Great Lakes. [53] Lake-effect precipitation produces a significant difference between the snowfall around the Great Lakes, sometimes within small distances.
