Sentences with phrase «interannual precipitation variability»

Satellite measures of vegetation greenness, together with animal stocking data and key climatic factors, reveal interannual precipitation variability to be a significant constraint on global pasture productivity.

Importantly, the changes in cereal yield projected for the 2020s and 2080s are driven by GHG - induced climate change and likely do not fully capture interannual precipitation variability which can result in large yield reductions during dry periods, as the IPCC (Christensen et al., 2007) states: ``... there is less confidence in the ability of the AOGCMs (atmosphere - ocean general circulation models) to generate interannual variability in the SSTs (sea surface temperatures) of the type known to affect African rainfall, as evidenced by the fact that very few AOGCMs produce droughts comparable in magnitude to the Sahel droughts of the 1970s and 1980s.»

Not exact matches

The ENSO phenomenon is one of the key factors that influence the interannual variability of precipitation over Southern South America.

Karl et al. [1995] examined precipitation records over the 20th century and showed that the high - frequency (up to interannual) variability has increased.

The large interannual to decadal hydroclimatic variability in winter precipitation is highly influenced by sea surface temperature (SST) anomalies in the tropical Pacific Ocean and associated changes in large - scale atmospheric circulation patterns [16].

Most model results project increased interannual variability in season - averaged Asian monsoon precipitation associated with an increase in its long - term mean value (e.g., Hu et al., 2000b; Räisänen, 2002; Meehl and Arblaster, 2003).

Links between interannual variability of extreme precipitation and temperatures offer possible observational constraints, especially since the underlying physical mechanisms are relatively well understood (e.g., O'Gorman and Schneider, 2009).

The statistics would be more robust with seasonal temperatures than with precipitation for sure because precipitation has a lot more interannual variability.

In multi-year ensemble simulations driven by reanalyses of atmospheric observations, Vidale et al. (2003) show that RCMs have skill in reproducing interannual variability in precipitation and surface air temperature.

IPCC projections do not show obvious threshold behavior this century (12), but they do agree that sulfate aerosols would dampen the strength of ISM precipitation, whereas increased greenhouse gases increase the interannual variability of daily precipitation (69).
