Sentences with phrase «increased monsoon precipitation»

However, the relative cooling effect of sulphate aerosols is dominated by the effects of increasing greenhouse gases by the end of the 21st century in the SRES marker scenarios (Figure 10.26), leading to the increased monsoon precipitation at the end of the 21st century in these scenarios (see Section 10.3.2.3).

Meehl and Arblaster (2003) relate the increased monsoon precipitation variability to increased variability in evaporation and precipitation in the Pacific due to increased SSTs.

Not exact matches

The monsoon precipitation intensified, and the increase caused erosion along the Tibetan Plateau and lower elevation areas nearby in what today is China, researchers found.

So while the monsoon winds might weaken the precipitation nonetheless increases (more bang for the buck) as a weaker circulation carries more water vapor (and latent energy).

Previous general circulation models have suggested that the monsoons were simply shifting later, with decreased rains through July but increased precipitation in September and October.

The main dynamical driver of the monsoon is therefore the positive moisture - advection feedback (Fig. 1 A): The release of latent heat from precipitation over land adds to the temperature difference between land and ocean, thus driving stronger winds from ocean to land and increasing in this way landward advection of moisture, which leads to enhanced precipitation and associated release of latent heat.

The inability of global climate models to match the timing or placement of short - term or regional precipitation patterns such as the West African monsoon may be alleviated by «downscaling» to use smaller scale climate models with increased area resolution.

Increased southern East Asian summer monsoon (SEASM) precipitation is related to warm WNP SST anomalies which create a weaker WNP anticyclone.

This increases precipitation during the summer African monsoon season.

The prominent upward trend in the GM precipitation occurring in the last century and the notable strengthening of the global monsoon in the last 30 yr (1961 — 90) appear unprecedented and are due possibly in part to the increase of atmospheric carbon dioxide concentration, though the authors» simulations of the effects from recent warming may be overestimated without considering the negative feedbacks from aerosols.

Model simulations of the Asian monsoon project that the sulphate aerosols» direct effect reduces the magnitude of precipitation change compared with the case of only greenhouse gas increases (Emori et al., 1999; Roeckner et al., 1999; Lal and Singh, 2001).

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).

In the tropics, an increase in precipitation is projected by the end of the 21st century in the Asian monsoon and the southern part of the West African monsoon with some decreases in the Sahel in northern summer (Cook and Vizy, 2006), as well as increases in the Australian monsoon in southern summer in a warmer climate (Figure 10.9).

Together with the progressive shortening of the ISM season and gradual southward retreat of the summer ITCZ, the total amount of monsoon precipitation decreased in those areas located at the northern fringe of the ISM domain, but increased in areas closer to the equator.

The fourth assessment report of the IPCC had this to say about the monsoon: «It is likely that warming associated with increasing greenhouse gas concentrations will cause an increase of Asian summer monsoon precipitation variability.

It can also strengthen the Asian summer monsoon circulation and cause a local increase in precipitation, despite the global reduction of evaporation that compensates aerosol radiative heating at the surface (Miller et al., 2004b).

In its projection for South Asia, the technical summary of the report clearly points at «enhanced summer monsoon precipitation and increased rainfall extremes of landfall cyclones on the coasts of the Bay of Bengal and Arabian Sea».

This event is associated with cold and dry conditions increasing with latitude in the North, temperature and precipitation influences on tropical and boreal wetlands, Siberian - like winters in much of the North Atlantic, weakening of monsoon intensity, and southward displacement of tropical rainfall patterns.

«Many anticipated adverse impacts of climate change including sea level rise, higher temperatures, enhanced monsoon precipitation and run - off, potentially reduced dry season precipitation, and an increase in cyclone intensity would in fact aggravate many of the existing stresses that already pose a serious impediment to the process economic development of Bangladesh.

Our experiments show that the solar cycle influences tropospheric rainfall patterns in a manner consistent with some observations, with increased solar activity favoring precipitation north of the equator (for example, the South Asian monsoon) and decreased precipitation both near the equator and at northern mid-latitudes.

«With an early arrival of monsoon - like atmospheric circulation in June, the heavy precipitation that occurred in northern India was a once - in - a-century event; however, analyses of observed and simulated June precipitation provide evidence that human - caused climate change has increased the likelihood of such an event.»

In summary, an intensification of the Asian summer monsoon and an enhancement of summer monsoon precipitation variability with increased greenhouse gases that was reported in the SAR has been corroborated by new studies.
