Active and Break Spells of the Indian Summer Monsoon
Sub-seasonal rainfall fluctuations, characterized as active and weak spells during the Indian monsoon season (June to September) is an important component of the variability of the Indian monsoon rainfall.

Effects of simulated daily precipitation patterns on annual plant populations
To improve the understanding of consequences of climate change for annual plant communities, the author used a detailed, grid-based model that simulates the effect of daily rainfall variability on individual plants in five climatic regions on a gradient from 100 to 800 mm mean annual precipitation (MAP). The model explicitly considers moisture storage in the soil. The researcher manipulated daily rainfall variability by changing the daily mean rain (DMR, rain volume on rainy days averaged across years for each day of the year) by

Prioritizing climate change adaptation needs for food security in 2030
Investments aimed at improving agricultural adaptation to climate change inevitably favor some crops and regions over others. An analysis of climate risks for crops in 12 food-insecure regions was conducted to identify adaptation priorities, based on statistical crop models and climate projections for 2030 from 20 general circulation models.

Food security under climate change
Some of the most profound and direct impacts of climate change over the next few decades will be on agricultural and food systems. A research by Lobell et al show that increasing temperatures and declining precipitation over semiarid regions are likely to reduce yields for corn, wheat, rice, and other primary crops in the next two decades. These changes could have a substantial impact on global food security.

The mysterious workings of the rain cloud
Contrary to what it says in the song, the rain in Spain does not stay mainly in the plain. It falls mostly in the mountainous regions of Cantabria and Asturias. Ask meteorologists why, and they will explain that the prevailing winds pick up moisture over the Atlantic, and that when this moist air hits Spain's northern mountain ranges it is forced up to higher altitudes, where the moisture condenses to form clouds, and then rain. So far so good - except that it's only half an answer.

Southern China faces the worst drought
Large swathes of the usually humid southern China are currently facing drought, described as the worst in 50 years. The drought has left over a million people short of drinking water and has shrunk

Climate change, deforestation and the fate of the Amazon
The forest biome of Amazonia is one of Earth's greatest biological treasures and a major component of the Earth system. This century, it faces the dual threats of deforestation and stress from climate change. In this article, the authors summarize some of the latest findings and thinking on these threats, explore the consequences for the forest ecosystem and its human residents, and outline options for the future of Amazonia.

Extreme rainfall analysis and estimation of Probable Maximum Precipitation (PMP) by statistical methods over the Indus river
Annual extreme rainfall series of 1-3 day durations at stations located inside the Indus basin in India were subjected to statistical analysis in order to estimate point Probable Maximum Precipitation (PMP) and maximum rainfall of different return periods for the durations of 1-3 days.

Resolving an atmospheric enigma
In 1971, meteorologists Roland Madden and Paul Julian studied weather data from near equatorial Pacific islands. To their surprise, tropospheric winds, pressure and rainfall oscillated with a period of about 40 to 50 days.
