Challenge of the summer rainfall forecast skill in China: A possible solution
The Mongolian Cyclone is a major meteorological driving force across southeast Asia. This cyclone is known for transporting aerosols, affecting where precipitation develops. Meteorologists are seeking ways to improve seasonal prediction of the relationship between the Mongolian cyclone and South Asia high. These features are major components of the East Asian summer monsoon (EASM) and the corresponding heavy rain events. New research suggests that analyzing these phenomena in the upper-level atmosphere will enhance the summer rainfall forecast skill in China. (2021-02-16)

Scientists propose three-step method to reverse significant reforestation side effect
Reforestation efforts using a monoculture of a fast-growing tree species, while effective, significantly impact the soil water content of humid, tropical regions and threatens global freshwater supplies. Scientists have now found that the transpiration rate and transpiration-related trait values are up to 10 times greater in the fast-growing species than nearby, dominant slow-growing species. The team has proposed a three-step method for ensuring reforestation efforts in tropical regions don't harm the surrounding soil water content. (2021-02-10)

Tracking the Himalayan history from the evolution of hundreds of frogs, lizards and snakes
We examined two hypotheses about the uplift of the Himalaya based on biotic assembly through time of the herpetofauna. Our analyses support a recently proposed stepwise geological model of Himalayan uplift beginning in the Paleocene, with a subsequent rapid increase of uplifting during the Miocene, finally giving rise to the intensification of the modern South Asia Monsoon. These series of geological and climatic events have left significant signal on the evolution of herpetofauna. (2020-10-26)

Indian monsoon can be predicted better after volcanic eruptions
Large volcanic eruptions can help to forecast the monsoon over India - the seasonal rainfall that is key for the country's agriculture and thus for feeding one billion people. As erratic as they are, volcanic eruptions improve the predictability, an Indian-German research team finds. What seems to be a paradox is in fact due to a stronger coupling between the monsoon over large parts of South and South-East Asia and the El NiƱo phenomenon after an eruption. (2020-09-18)

Scientists look into tropopause to find early signals of persistent strong rainfall
10 days before the peak rainfall, the joint action of the South Asia high and the Okhotsk Sea blocking high compresses the anomaly cold air between the two highs, and forms a narrow and steady cold air transport channel on the inclined isentropic surface. (2020-09-16)
