Methane hydrates are believed to form by migration of gas from deep along geological faults,
followed by precipitation or crystallization, on contact of the rising gas stream with cold sea water.

For example, [Kruss 1983] has this to say about the Lewis glacier on Mt. Kenya: «A decrease in the annual
precipitation on the order of 150 mm in the last quarter of the 19th century,
followed by a secular air temperature rise of a few tenths of a degree centigrade during the first half of the 20th century, together with associated albedo and cloudiness variation, constitute the most likely cause of the Lewis Glacier wastage during the last 100 years.»
But changes in
precipitation in the region — brought about
by a combination of deforestation and warmer temperatures — are making things difficult to
follow their traditional ways.
Our study has not been
followed up
by experts in the observational community, and even if there is no Iris it would be interesting to know what is the sea surface temperature dependence of the
precipitation efficiency in tropical clouds.
Because the model only describes the rainy season and does not capture the annual monsoon cycle, abrupt transitions in the bistable regime can only be interpreted intraseasonally, e.g., a month of heavy rain
followed by a month of extraordinarily weak
precipitation.
You'll have drought
followed by freak
precipitation events because of the increased condensation that is linked to warmer temperatures.
«Even though California historically has periods of dry and wet years, there isn't an analog for climate extremes like the ones we've observed in recent years, such as those record - breaking prolonged periods of drought
following by periods of intense
precipitation pulses that cause flooding,» Woodburn said.
As researchers documented in this graph, the region had experienced increasing
precipitation during the Little Ice Age,
followed by a sharp drying trend that began in the late 1700s, which triggered Kilimanjaro's retreat long before CO2 ever reached significant concentrations.
Leaf area index, which is also enhanced
by increasing atmospheric carbon dioxide, was the second most important factor, contributing an additional 21.8 percent,
followed by climate change (
precipitation and air temperature together) and the fraction of photosynthetically active radiation, which accounted for the remaining 18.3 and 14.6 percent increase in NPP, respectively.
The first kind of
precipitation whiplash is from year to year, meaning that we'll see more extraordinarily dry years
followed by incredibly wet years — in the way California's five - year drought ended in 2017 in one of the wettest winters on record.
[ISPM 2.2 a] This is
followed by a few examples of inconsistent regional trends, as well as a statement concerning a lack of trend in overall total
precipitation.
In our simulations, when
precipitation fell below average, the trees quickly shed foliage to adapt to the drier conditions, and tree vigor was negatively affected
by the sudden drop in leaf area as indicated
by the decrease in the
following year's GE (ratio of change in the change in LAI to stem diameter).
According to Neilson, the latest models suggest that parts of the US are experiencing longer - term
precipitation patterns, with less year - to - year variability but several wet years in a row
followed by several years that are drier than normal.
Volatile
precipitation patterns, with heavy rains
followed by drought, can lead to ideal conditions for wildfires in some states.

by precipitation:
Anna Michalak's team combined sampling and satellite - based observations of Lake Erie with computer simulations and determined that the 2011 record - breaking algal bloom in the lake was triggered
by long - term agricultural practices coupled with extreme
precipitation,
followed by weak lake circulation and warm temperatures.

precipitation -LSB-...] It is more probable that forests will be replaced
by ecosystems -LSB-...] such as tropical savannas.»
