Scientist works to puzzle out how tropical rainfall will change with a warming planet Stephanie Paige Ogburn, EE reporter Published: Thursday, April 18, 2013 For scientist Shang-Ping Xie, there is a good reason to research how climate change will alter weather patterns in the tropics, even if, to most of us, tropical regions seem remote. What happens in the tropics, Xie -- a professor at the Scripps Institution of Oceanography at the University of California, San Diego, and the International Pacific Research Center at the University of Hawaii, Manoa -- noted in a recent interview, is highly influential on midlatitude climate. Much of North America sits in those middle latitudes. Rainfall and temperatures here, Xie pointed out, can be greatly influenced by tropical climate phenomena like El Ni漀 and La Ni愀. So it's in our interest to understand what the tropics are up to. But beyond what happens in Americans' backyards, there are many other reasons for caring about tropical climate and weather patterns. Most of the world's population lives in the tropics. And much of the farming that goes on in tropical regions relies heavily on seasonal rainfall -- monsoons -- which may shift or change as the climate changes. Xie is among many scientists working to understand how climate change will affect that rainfall. In a paper published Sunday in Nature Geoscience , he and his colleagues proposed a way to reconcile two different views of how tropical rainfall will change as the climate changes. The first, known as the rich get richer or wet get wetter hypothesis, posits that tropical areas that already get a lot of rain will get even more as the world warms, and dry subtropical areas will get less. According to David Neelin, a researcher at UCLA, the basic idea behind this view is that warmer atmospheres hold more moisture. This is likely to enhance the patterns that already exist for rainfall. There is a tendency for the rain in rainfall events to increase, Neelin said. Interplay of two theories The second hypothesis is called warmer get wetter. As Xie explains it, the focus in this view is that ocean temperatures are going to increase, but not in a uniform way, as the climate changes. The places where the ocean's surface gets warmer will, as in the other scenario, have more moisture and thus get more rainfall. But where this ocean warming is going to happen is unknown at this point, Xie said, and is another focus of his research. In the paper, Xie and his colleagues show how both the wet get wetter and warmer get wetter hypotheses can work as explanations for what will happen to tropical rainfall in a warming world. When the researcher ran models looking at what would happen to rainfall in the tropics, the wet areas did get wetter, but primarily in the monsoon times of year. So the wet areas got wetter during their rainy seasons. UCLA's Neelin said this agreed with what he would expect to see happen under a wet get wetter scenario. Xie also found that areas where the oceans warmed got wetter, but in their annual rainfall: the amount of rain that fell over the course of the entire year. Massimo Bollasina, a postdoctoral research associate at the National Oceanic and Atmospheric Administration's Geophysical Fluid Dynamics Laboratory who also works on tropical rainfall and climate change, called Xie's paper a very reasonable analysis of how the two hypotheses interplay. Picture for small regions remains 'messy' Understanding what will happen to monsoon rains, particularly in places like India, where agriculture depends on them, is extremely important, Bollasina said. Bollasina was careful to point out, as were Xie and Neelin, that although these hypotheses might play out on the large scale, making them useful for climate models, regionally there are many other factors that will affect tropical rainfall as the climate changes. The whole rich get richer mechanism is a good explanation at somewhat larger scales, like when you are talking about an average over a whole convection zone, a whole monsoon area or a fairly large region, Neelin said. Small countries or states, though, might see different outcomes, especially if they are on the edge of wet or dry. We are really doing the broadest brush at this point, Xie said. In climate, if you average over a larger area, you can reduce uncertainties, so that's a trick we employed. Because if you come to a small region like New Mexico or Arizona , a lot of other things are going to come into play. Things become messy, and we don't want them to be messy at this point, he said.
Public release date: 15-Apr-2013 Contact: Gisela Speidel gspeidel@hawaii.edu 808-956-9252 University of Hawaii SOEST Study reveals seasonal patterns of tropical rainfall changes from global warming IMAGE: Rain clouds form over the tropical ocean. Click here for more information. Projections of rainfall changes from global warming have been very uncertain because scientists could not determine how two different mechanisms will impact rainfall. The two mechanisms turn out to complement each other and together shape the spatial distribution of seasonal rainfall in the tropics, according to the study of a group of Chinese and Hawaii scientists that is published in the April 14, 2013, online issue of Nature Geoscience . The one mechanism, called wet-gets-wetter, predicts that rainfall should increase in regions that already have much rain, with a tendency for dry regions to get dryer. The second mechanism, called the warmer-gets-wetter, predicts rainfall should increase in regions where sea surface temperature rises above the tropical average warming. The team of scientists compared current rainfall in the tropics with future rainfall projections from simulations of 18 cutting-edge climate models forced with a likely scenario of atmospheric greenhouse gas concentrations. They found that rainfall in the models increases more in regions that currently are already wet and decreases slightly in currently dry regions, supporting the wet-gets-wetter mechanism. But they also found evidence for the warmer-gets-wetter mechanism in that the higher the surface temperature in a region, the more the rainfall. By merging the impact from the two mechanisms, they noted that they could account for nearly 80 percent of the variations in the models' projected rainfall changes from global warming. The complementary action of the two mechanisms is because the pattern of ocean warming induces more convection and rainfall near the Equator, where the temperature warming peaks, and subsidence and drying further away from the Equator, reflecting the warmer-gets-wetter view. But as this band of increased rain marches back and forth across the Equator with the Sun, it causes seasonal rainfall anomalies that follow the wet-gets-wetter pattern. The wet-gets-wetter mechanism contributes more to the projected seasonal rainfall changes, whereas the warmer-gets-warmer mechanism more to the mean annual rainfall changes. Because our present observations of seasonal rainfall are much more reliable than the future sea surface temperatures, we can trust the models' projections of seasonal mean rainfall for regional patterns more than their annual mean projections, says co-author Shang-Ping Xie, meteorology professor at the International Pacific Research Center, University of Hawaii at Manoa and Roger Revelle Professor at Scripps Institution of Oceanography, University of California at San Diego. This is good news for monsoon regions where rainfall by definition is seasonal and limited to a short rainy season. Many highly populated countries under monsoon influences already face water shortages. ### Citation: Ping Huang, Shang-Ping Xie, Kaiming Hu, Gang Huang, Ronghui Huang: Patterns of the seasonal response of tropical rainfall to global warming.

Jankowski, Christopher L. Merkord, William Farfan Rios, Karina García Cabrera, Norma Salinas Revilla, Miles R. Silman Abstract Aim Understanding patterns of species turnover along environmental gradients and their consistency across taxonomic groups is central to the study of biodiversity. We may expect congruence in diversity patterns across groups whose ranges could be influenced by species interactions. We explore associations between bird and vegetation communities in the tropical Andes to determine whether patterns of species richness and turnover in birds and trees are congruent with elevation, and whether tree species composition, vegetation structure, elevation, or a combination of these best predicts bird species composition. Location A forested 2600-m elevational gradient on the eastern slope of the Peruvian Andes. Methods Bird surveys and vegetation measurements were conducted at 172 points, and a subset of these were spatially matched with fourteen 1-ha tree inventory plots. Diversity patterns were described for trees, birds, and avian foraging guilds. We used dissimilarity matrices to examine patterns of turnover and nestedness. Turnover of birds and trees was examined by comparing compositional change of adjacent plots along the gradient. Multiple regression on distance matrices was employed to determine contributions of tree species composition, vegetation structure and elevation to explaining variation in bird species composition. Results Species richness was higher for trees than for birds, and whereas diversity in both taxa decreased with elevation, tree richness showed a low-elevation plateau before declining at higher elevations. Tree species had narrower distributions compared to birds, but patterns of turnover were largely congruent between taxa. Nestedness contributed much less to dissimilarity than turnover, although birds showed higher nestedness, particularly at high elevations. Tree species composition, elevation and vegetation structure were all important predictors of bird species composition; the best model explained 78% of bird dissimilarity across plots. Tree species composition was always included in the best models, for all birds and foraging guilds. Main conclusions Our assessment of Andean bird and vegetation communities suggests strong correspondence, perhaps due to direct interactions or similar underlying drivers. We hypothesize that with climate change, range shifts in these groups may not occur independently. Rather, birds may have delayed upslope shifts or may be limited to high-elevation patches where appropriate vegetation communities exist.
New Report on “Neglected” Tropical Diseases Thank you for your interest in the Global Research Reports from Thomson Reuters. We are writing to inform you that a new report has just been released by the Intellectual Property Science business of Thomson Reuters. The new study reports evidence of growing interest in research and control of neglected tropical diseases across countries and fields. It provides important insights for policymakers and others concerned with public health. Neglected Tropical Diseases analyzes research output from 1992 to 2011 for a group of diseases identified by the World Health Organization as underserved by public health services. These diseases infect more than one billion people around the globe and are responsible for over half a million deaths annually. While the study finds a two-fold increase in published literature since 1992, the totals still pale in comparison to those for diseases such as cancer, HIV/AIDS, and coronary artery disease. In addition to bibliographic analysis, the report also reviews research by region and individual disease, yielding clues to strategies for fostering more research: Of the four nations represented in the most neglected tropical disease research, Brazil and India have the steepest growth in new research. Of the specific diseases cited most frequently in published research over the last 20 years, Dengue research has shown the sharpest recent growth, nearly tripling in output between 2002 and 2011. Research into neglected tropical diseases appears to be evolving towards solutions that move from studying the disease toward creating remedies , as evidenced by a spread across journal categories from core biomedical areas to fields relating to the ecology of the disease and the social and health environment in which these diseases are prevalent.

Dear colleagues, As session convener and co-convener we would like to invite papers submission to a session entitled 'Recent Advances in the Science and Prediction of Tropical Cyclone' (AS21) in the coming Asia Oceania Geosciences Society 8th Annual Meeting during 8-12 August 2011 at Taipei, Taiwan. The other co-conveners include Dr. Yihong Duan of the National Meteorological Center of China, Prof. Russell Elsberry of the Naval Postgraduate School, and Dr. Hyun-Mee Kim of the Yonsei University of South Korea. The due for abstract submission is 15 March, which can be done through the meeting website at http://www.asiaoceania.org/aogs2011/ . The session description is at the end of this email for your reference. Thank you very much for your attention. Best regards, Chun-Chieh Wu (convener) Department of Atmospheric Sciences National Taiwan University Kevin Cheung (co-convener) Department of Environment and Geography Macquarie University, Australia Recent Advances in the Science and Prediction of Tropical Cyclone Tropical cyclone (TC), also known as hurricane in the Atlantic and typhoon in the western North Pacific in its mature stage, is one of the most devastating weather systems. The impacts from TCs are multiple in nature: Besides the direct threat from the strong winds, hazards are often brought by the torrential rainfall that causes flash flood, landslide and debris flow. Storm surge is another form of impact to the coastal areas. After decades of research effort, the theory of TC motion is quite mature. However, it is generally recognized that the problem is not completely solved yet because occasionally there are still cases of large TC track forecast errors from numerical models, especially when topographic effect is involved. Recent focuses of research include TC formation, intensity, rapid intensification, TC structure change, associated rainfall, landfall processes, extratropical transition and interaction with midlatitude systems. In-situ observations such as those from aircraft reconnaissance/surveillance programs (such as T-PARC), improvements in utilization of satellite data as well as those in numerical models all contribute to the advances of the science and prediction skill. Furthermore, climate variability of long-term TC activity is another active area of research in view of the possible contribution from anthropogenic climate change to more intense storms. Focuses in this aspect includes inherent data problems and capability of climate models in projecting future TC behavior. This session aims to create a platform for discussing recent advances in the aforementioned areas. Observational and numerical modeling studies on TCs, their interaction with the environment and associated hazards in the Asia Oceania region as well as other ocean basins are also welcome.
