London: Britain has sweltered through the hottest day of the year so far, with temperatures soaring to 35 degrees in parts of the country.

Tropical cyclones play an important role in modifying the tropopause structure and dynamics as well as stratosphere–troposphere exchange (STE) processes in the upper troposphere and lower stratosphere (UTLS) region. In the present study, the impact of cyclones that occurred over the north Indian Ocean during 2007–2013 on the STE processes is quantified using satellite observations.

The reaction of clouds to a warming atmosphere has been one of the major sources of uncertainty in estimating exactly how much the world will heat up from the accumulation of greenhouse gases, as s

Tropopause temperatures (TPTs) control the amount of stratospheric water vapour, which influences chemistry, radiation and circulation in the stratosphere, and is also an important driver of surface climate. Decadal variability and long-term trends in tropical TPTs as well as stratospheric water vapour are largely unknown. Here, we present for the first time evidence, from reanalysis and state-of-the-art climate model simulations, of a link between decadal variability in tropical TPTs and the Pacific Decadal Oscillation (PDO).

For the first time, on the dimly glowing remnants of a failed star mere light-years from Earth, scientists have found evidence of water clouds beyond our solar system.

Clouds are moving towards the poles and getting higher in the sky as the planet warms, according to a new study that confirms predictions made by climate models for the first time.

Long-term measurements (from August 2009 to December 2014) of aerosol black carbon mass concentration (MBC) and spectral aerosol optical depth (AOD) were carried out from a high-altitude location, Hanle in western trans-Himalaya as part of the Regional Aerosol Warming Experiment.

We present the measurements of cloud-base height variations over Aryabhatta Research Institute of Observational Science, Nainital (79.45E, 29.37N, 1958 m amsl) obtained from Vaisala Ceilometer, during the nearly year-long Ganges Valley Aerosol Experiment (GVAX). The cloud-base measurements are analysed in conjunction with collocated measurements of rainfall, to study the possible contributions from different cloud types to the observed monsoonal rainfall during June to September 2011.

New research based on ocean models and near real-time data from autonomous gliders indicates that the "The Blob" and El Niño together strongly depressed productivity off the West Coast, with The Bl

Air pollutants interact with and break down plant-emitted scent molecules, which insect pollinators such as bees use to locate needed food, says a new study.
