A human body may be able to adapt to extremes of dry-bulb temperature (commonly referred to as simply temperature) through perspiration and associated evaporative cooling provided that the wet-bulb temperature (a combined measure of temperature and humidity or degree of ‘mugginess’) remains below a threshold of 35 °C. (ref. 1). This threshold defines a limit of survivability for a fit human under well-ventilated outdoor conditions and is lower for most people.

Upper-air radiosonde observations, taken during “Cloud Aerosol Interaction and Precipitation Enhancement EXperiment” (CAIPEEX) at Mahabubnagar (16.73°N, 77.98°E) under Integrated Ground Observation Campaign (IGOC) during the second half of southwest monsoon of 2011 have been analysed. Various weather data taken from India Meteorological Department as well as NCEP/NCAR reanalyzed upper-air wind data for the months August and September of 2011 have also been used in the study. Intra-seasonal variation of monsoon, during the period of experiment, has been studied.

The El Nino weather phenomenon, which has often disrupted rainfall in India, is further strengthening and likely to persist into early 2016, the Australia Bureau of Meteorology said in an update on

A positive phase of the Indian Ocean Dipole (IOD) may have already begun to play out, according to the Applications Laboratory of Jamstec, the Japanese national weather forecaster.

SSNNL stated that it had consulted state-level Environmental Clearance Assessment Authority in 2010 which stated that no environ mental clearance was required.

Change in characteristics of Arabian Sea, say experts

Judgement of the National Green Tribunal (Western Zone Bench, Pune) in the matter of Maria Filomena Furtado & Others Vs Goa Coastal Zone Management Authority & Others dated 02/07/2015 regarding violations of CRZ Notification, 1991.

The monsoon will arrive in Kerala on May 30, but may be weak because of El Nino, India Meteorological Department (IMD) scientists have indicated.

Unprecedented, widespread, and devastating hailstorms occurred during February and March 2014 over north peninsular India (study area). A diagnostic study has been carried out to understand the causes for the same. Over the study area the atmosphere was convectively unstable due to the incursion of warm and moist air from Bay of Bengal and Arabian Sea which was overlaid by cold and dry midlatitude westerlies caused due to the unusual upper oceanic heat content of the Pacific Ocean.

Ground and satellite based measurements of spectral optical properties of aerosols have been carried out at Dehradun (DDN) in the Indo-Gangetic Plain (IGP) and Kavaratti (KVT) at Lakshadweep in southern Arabian Sea during pre-monsoon season (March–May) 2012. The measurements illustrate distinct seasonal impact on aerosol properties with maximum dust loading during May in conjunction with anthropogenic aerosols over DDN and marine aerosols over KVT.
