Sentences with phrase «global circulation models»

The research will enable better predictions of these climate forces in global circulation models.

Output from global circulation models indicates that climate variability will continue to be an important characteristic of the region in the future [52], but that climate change may increase the risk of extreme climatic events such as multi-decade droughts and extreme winter precipitation [53], [54].

A recent analysis used global circulation models to study the future of more than 2,100 lakes.

For example, the existing global circulation models do not adequately describe the water cycle in the Amazon, with the modeled moisture convergence being half the actual amounts estimated from the observed runoff values.

The new findings, based on detailed computer simulations using the best available global circulation models, are described this week in the journal Science Advances, in a paper by MIT professor of environmental engineering Elfatih Eltahir, MIT Research Scientist Eun Soon Im, and Professor Jeremy Pal at Loyola Marymount University in Los Angeles.

However, neither convective drafts nor spatial cloud structure are explicitly resolved by coarse - resolution global circulation models, so the convective vertical transport of hydrometeors (all forms of precipitation) must be parameterized.

That's why we end up using much more complex models (like Global Circulation Models) but these basic energy balance models do still provide useful information.

It made use of a new technique to add finer - scale detail to computer simulations called Global Circulation Models, which are the basis for most projections of future climate change.

«In addition, we have shown here that global circulation models vary widely in their drought - frequency projections, particularly later in the century and along higher emissions scenarios,» said Yohe.

Trying to understand the global climate and how it has changed, is changing, and will likely change in the future requires climate models known as global circulation models (GCMs).

Further, all global circulation models studied portray this process as deeper and stronger than what is observed in field measurements.

Some global circulation models also project that mean winter precipitation in the Southwest will decline by up to 10 % [52], but it may take many years to detect effects on stream flows because of precipitation variability [55].
