Abstract
[1] Forced with increased greenhouse gases, the South Asian summer
monsoon (SASM) circulation weakens in climate models, which appears
inconsistent with the projected increases in near-surface land-sea
thermal contrasts during the 21st century. Our analysis shows that the
SASM intensity positively correlates with the land-sea thermal contrast
in both the lower- and upper-troposphere before year 2000; thereafter a
reduced upper-tropospheric thermal contrast leads to a weakened SASM
circulation, despite an increasing lower-tropospheric thermal contrast.
The decrease in the upper-tropospheric thermal contrast mainly results
from enhanced upper-tropospheric warming over the tropical Indian Ocean
due to increased latent heating. The results suggest a crucial role of
enhanced tropical convection in the weakening of SASM circulation and a
weak influence of lower-tropospheric thermal contrast on the SASM under
global warming. They also imply a less important role of near-surface
processes over the Tibetan Plateau in the long-term SASM change during
the 21st century.
Last paragraph from th conclusion,
" Because the enhanced upper-tropospheric warming results primarily from
increased latent heating from tropical convection, this study implies a
crucial role of increased water vapor in SASM’s response to increased
GHGs. Furthermore, despite the weakened monsoon winds, summer monsoon
precipitation in South Asia still increases in most GCMs because of the
increased water vapor content and convergence over the SASM region
[e.g., Ueda et al., 2006 <javascript:openreferences('ueda06')>].
Therefore, in the selected seven AR4 models both the increased monsoon
precipitation and the decreased monsoon winds in South Asia are mainly
caused by the increased water vapor and enhanced tropical convection in
a GHG-induced warmer climate."

FOR IMMEDIATE RELEASE
January 8, 2010
EPA Requests Grant Applications to Fight Climate Change
WASHINGTON – The U.S. Environmental Protection Agency (EPA) today
announced it is making up to $5 million in grants available to U.S.
and international organizations to fund innovative, international
methane reduction and use projects that cut global climate pollution.
The grants will be issued through the Methane to Markets Partnership,
a public-private partnership that reduces greenhouse gas (GHG)
pollution by promoting the cost-effective, near-term recovery and use
of methane, a GHG that is more than 20 times more potent than carbon
dioxide.
Methane capture and use projects supported by the partnership through
grants and other means are currently reducing emissions by more than
27.3 million metric tons of carbon dioxide equivalent annually –
equivalent to the annual emissions from 5 million passenger vehicles.
Non-profit or government organizations in any country may apply for
grant funding, but projects should take place in the following
Methane to Markets Partner countries: Argentina, Brazil, Chile,
China, Colombia, Dominican Republic, Ecuador, Georgia, India,
Kazakhstan, Republic of Korea, Mexico, Mongolia, Nigeria, Pakistan,
Philippines, Poland, Russia, Thailand, Ukraine, and Vietnam. If an
organization wishes to submit an application for a project in a
developing country or a country with an economy in transition that is
not listed above, the country must first apply to the Methane to
Markets Partnership before the project can be considered for funding.
Grant proposals should support feasibility studies, technology
transfer, deployment of technology, training, methane emissions
inventories, and other activities that promote methane capture and
use. The agency expects to award up to 35 cooperative assistance
agreements ranging from approximately $100,000 to $750,000.
Proposals are due by April 15, 2010, at 1:00 p.m. EST. EPA estimates
that awards would be made at the end of 2010.
Since the launch of the partnership in 2004, EPA has provided almost
$13 million for nearly 70 grants to build capacity and promote
international capture and use of methane. This work will be
highlighted in 2010 when EPA, the Government of India and the
Federation of Indian Chambers of Commerce and Industry host the 2nd
Methane to Markets Partnership Expo on March 2-5, 2010 in Delhi,
India. The expo will bring together approximately 1,000 partners and
methane experts from around the world to showcase project
opportunities and technologies related to the capture and use of
methane.
