Sentences with phrase «rain belt»

The tropical rain belt moves north and the southern hemisphere cools a bit, in some sort of bipolar see - saw response.
Those same lakes, along with other evidence from around the world, also points to the shifting of rain belts after a rapid loss of Arctic sea ice about 14,600 years ago that saw the Northern Hemisphere heat up faster than the Southern.
Expansion and contraction of the Indo - Pacific tropical rain belt over the last three millennia (Scientific Reports)
They also project a northward shift of the main rain belt that provides moisture to the Amazon rainforest, which could further reduce rainfall to the region.
A new study using a high - resolution stalagmite record from Australia with cave sites in southern China reveal a close coupling of monsoon rainfall on both continents, with numerous synchronous pluvial and drought periods, suggesting that the tropical rain belt expanded and contracted numerous times at multidecadal to centennial scales.
Because the Northern Hemisphere has more landmass, it is heating up faster than the Southern Hemisphere, and, as some climate models have suggested, this could push the thermal equator northward, and along with it those key rain belts.
This long - term change in the East Asian monsoon index is consistent with a tendency for a southward shift of the summer rain belt over eastern China (Zhai et al., 2004).
The school will be followed by the Workshop 2nd WCRP Grand Challenge Meeting on Monsoons and Tropical Rain Belts from July 2 to July 5, 2018.
Most rain on Earth falls in the tropical rain belt known as the Intertropical Convergence Zone (ITCZ), which on average lies 6 ° north of the equator.
The simulations captured a good deal of the expansion / contraction behavior (see figure) and suggested that the tropical rain belt appears particularly susceptible to Pacific ocean temperatures and volcanism.
But which regions are wet and dry are also determined by the locations of the Earth's main rain belts.
Their analysis revealed a close coupling of monsoon rainfall on both continents, with numerous synchronous pluvial and drought periods, suggesting that the tropical rain belt expanded and contracted numerous times at multidecadal to centennial scales.
These and other paleoclimate records indicate that rain belts shifted northward along with the thermal equator because of the global heat imbalance.
A new study by Denniston, Ummenhofer, and colleagues integrated a high - resolution stalagmite record from Australia with cave sites in southern China to reconstruct the behavior of the tropical rain belt over the last 3000 years.
Numerous stalagmite studies have examined variations in monsoon rainfall over previous millennia in China at the northern margin of the Indo - Pacific tropical rain belt, but only a handful of studies have focused on its southern margin.
As the Northern Hemisphere warms faster than the Southern, Earth's rain belts may shift to the North
Putnam said the study was more focused on how the difference in warming between the hemispheres impacted the rain belts.
Kevin Trenbeth, a climate scientist at the National Center for Atmospheric Research in Boulder, Colo., said the study didn't account for changes in sea surface temperatures, which are the main drivers of changes in the position of the rain belts (as is seen during an El Nino event, when Pacific warming pushes the subtropical jet over the Western U.S. southward).
A new study that does just that suggests that Earth's rain belts could be pushed northward as the Northern Hemisphere heats up faster than the Southern Hemisphere.
The positions of those rain belts, in turn, are tied to that of the so - called thermal equator (the ring around the planet's middle where surface temperatures are highest).
What this could mean, the authors posit, is that as the boreal winter continues to warm disproportionately, the thermal equator and therefore the rain belts won't travel as far south as they currently do during the winter.
«The iceberg surges push the rain belts, or the tropical climate system, to the south and the impact on climate can be rather significant.»
Sulfurous gases released into the atmosphere impacted monsoon rainfall in the Ethiopian highlands, weakening the rain belt system and, as a result, depleting the flow of water to the river.
Individual records from caves and other paleo - hydroclimate proxies have implied that simultaneous drying of the Northern tropics and wetting of the Southern tropics followed Heinrich events, consistent with southward shifts of the tropical rain belts and the thermal equator.
The worst scenario is the scenario we've been talking about for an hour — we're warming the planet and we're shifting the rain belt and we're going to have to do something that we probably never dreamed we'd do, which is put SO2 into the atmosphere.
Reconstructing past dynamics of the tropical rain belt is important for understanding how the width of the tropics may respond to future climate change.
The seasonal migration of summer monsoon rains across the equator defines the tropical rain belt, a zone of enormous biodiversity and the home of approximately 40 % of people on Earth.
«Just a few hundred kilometers separates the Sahara Desert from the African rainforests, so even a small shift of the tropical rain belt can have a devastating effect,» notes Frierson.
According to Delworth, in monsoon - dependent regions stretching from Africa to India, the changing AMOC will «move the tropical rain belts further north, so the Sahel of Africa will see the mean rainfall decrease as those rain belts move further north as the North Atlantic warms, while a colder North Atlantic pushes the rain belts further south.»
With that the monsoon moves southward and with that the tropical rain belt.
