Below 10,000 feet they are wettest on their southeastern and southern sides, with annual total precipitation rising to 100 inches on Mount Kenya; they are driest on their northern flanks, with less than 40 inches of rainfall yearly.
Even with a fixed amount of precipitation, rising surface air temperatures cause a reduction in the fraction of annual precipitation stored as snow, and a shift in the timing of runoff to earlier dates in the spring.
Agriculture of subsistence food crops and crops for export may be adversely affected by changes in precipitation, rising temperatures causing heat stress to plants, salinization resulting from sea-level rise, and extreme weather and climate events, such as cyclones, floods, or droughts.
Severe drought is common in the hottest summers, such as those of 1934, 1954, 1980 and 2011, all of which featured weeks on end of virtual rainlessness and high temperatures well over 100 degrees F. Average precipitation rises again from September to mid-October, representing a secondary wetter season, then declines from late October through December.
Falling temperatures and precipitation are rising concerns as the N.F.L. heads toward the playoffs.
However, there are emergent patterns in the day-to-day persistence (declining) and mean precipitation yield (rising) of anticyclonic weather types that merit further investigation.
In Kenya at the moment, downstream information regarding these circumstances remain scanty, with many smallholders being 'on their own', in spite of the imminent threats from shifting precipitation patterns, rising temperatures, and intensifying droughts.
Observed changes in precipitation patterns, rising surface temperature, increases in frequency and intensity of floods and droughts, widespread melting of ice, and reduced snow cover are some of the documented hydrologic changes associated with global climate change.
It is why we will band together to do all we can for Texas, and why we will be there for all Floridians, even those like Rush Limbaugh who deny the clear science that climate change exposes us to increased risk of giant precipitation events, rising sea levels, and lethal forest fires. .
These sources are climate sensitive, and changes in precipitation or rising sea levels will present challenges to public health.
At elevations of 13,000 feet (4,000 metres), precipitation levels rise to some 160 inches (4,000 mm), and the Mönch (13,448 feet [4,099 metres]) in the Jungfrau group of mountains has the highest average annual precipitation in Switzerland, 163 inches (4,140 mm), while Stalden in the entrenched Vispa valley, 4 miles (6 km) south of the main Rhône valley, has the lowest, 21 inches (533 mm).
