An increase in short duration precipitation extremes pose challenges for stormwater design in rapidly urbanizing India. The recent Paris Agreement aims to limit the global mean temperature (GMT) below 1.5 °C (and possibly below 2.0°C) from the pre‐industrial level. However, the changes in sub‐daily precipitation extremes in India remain unrecognized …
The meteorological department records that some 60 mm of rain has fallen in just about 6 hours; 90 mm in 24 hours; and with this the city has made up for its deficit of rainfall this season. In other words, in just about 24 hours Delhi and its surrounding areas …
The national climate change policy provides a framework for addressing the issues that Pakistan faces or will face in future due to the changing climate. In view of Pakistan’s high vulnerability to adverse impacts of climate, in particular extreme events, adaptation effort is the main focus of this policy document. …
TWO recent studies have clinched enough empirical data to repudiate any climate change sceptic. For the first time, the studies have pinned down greenhouse gas (GHG) emissions for frequent extreme weather events like rainfall and floods. In one study, UK and Switzerland researchers analysed one of the worst floods in …
As I write this piece, the finance minister has dispatched the Union Budget 2011. The press is busy reflecting the views of business and industry lobbies, as they quibble over duty exemptions, insist on financial stimulus and other incentives, and cry for big-ticket reform—foreign direct investment in retail and insurance. …
THE government should offer assured income to farmers and shield them from erratic weather conditions. These are a few of the demands of farmers’ groups from the Union Budget 2011-12, which will be tabled in February-end. To address the declining growth in agriculture, the government should allocate more funds for …
The World Economic Forum—the gathering of power glitterati each year in Davos—has assessed the top risks the world faces in 2011. According to this analysis, climate change is the highest-ranking risk the world will face in the coming years, when its likelihood and impact are combined. What’s even more important …
EXTREME weather conditions over the past few weeks have destroyed crops in several states, triggering farmers’ suicides. In all, over 300 farmers reportedly killed themselves in Andhra Pradesh (275), Odisha (36) and Madhya Pradesh (7), the worst hit states. Media reports said some of the deaths were caused by heart …
SEVERAL countries in the Southern Hemisphere experienced their worst floods in decades in the past two months. While intense rainfall for over a month kept parts of Australia inundated for weeks, severe floods and landslides killed hundreds of people in Brazil and Sri Lanka, and affected more than one million. …
On a brief visit to Pakistan this week I noted that the recent floods have left deep impressions on the country’s policy and political leadership. They spoke about the scale of devastation, human suffering and the massive challenge of rehabilitation. They also noted, interestingly, that in their view there was …
A cloud burst over arid Himalayan town of Leh in Ladakh on August 6, pouring some 250 mm of rain in an hour. The sudden downpour triggered flash floods and mudslides, killing over 180 people and wiping out the old town of Leh and two villages. Weathermen say the high-altitude …
Cloudbursts are usually triggered by mountain formations that lead to lifting of moisture-laden winds and forming of a convective cloud. Cloudbursts are common in the western Himalaya. Western disturbances over the Leh region on August 5 might have also triggered the cloudburst, said M Rajeevan, of National Atmospheric Research Laboratory, …
Meteorology isn't what it used to be predicting monsoons may become costlier now. An increase in the frequency of extreme weather events like intense rainfall has magnified the errors in observations and calculations required for predicting the weather. Chances for an error occurring depend on these parameters: the location of …
The authors in this paper present a factual and a brief review of the extreme weather events that occurred in India during the last 100 years (1991-2004). The socio-economic impacts of the extreme weather events such as floods, droughts, cyclones, hail storm, thunderstorm, heat and cold waves have been increasing …
