People in vulnerable areas should already know their local evacuation procedure.

Read my op-ed on why we need "disaster preparedness drills" along with this article by Nirajan Siwakoti on how quick decision making and dissemination of danger helped save a few lives during the Tibet-Nepal floods.

theconversation.com Nepal’s devastating floods: 10 seconds could save lives Could more lives be saved if people were trained to act immediately when a flood warning arrives? I believe the answer is yes.

In India, everyone needs a disaster drill.

My op-ed in today’s Indian Express on why every school, college, workplace and community should hold mandatory seasonal disaster drills, with one before the heatwave season and another before the monsoon.

Heat will be harder to escape by 2050, when many of us will be older and more vulnerable. Add about 25 years to your age now. Are you prepared!

Harder to escape, both in space and time.

We come home from a hot day outdoors, expecting relief, but the heat is already in the bedroom, since our housing and urban setup trap the heat. And the nights are getting warmer, and rising humidity makes it harder for our bodies to cool.

The good news is that the data help us understand these risks and protect ourselves better. We need to learn how to grow older in a hotter world.

The monsoon index plotted here shows that the monsoon winds and circulation during the June-September season this year was relatively weak (compared to climatological mean).

The monsoon winds/circulation were relatively weak and less organized this season. This gave a chance for low pressure systems from the Bay of Bengal and Western Disturbances (WDs) to bring in rains (heavy rains possibly due to intensified water cycle), compensating rainfall deficits over some of the states.

Pune rains here exemplify the monsoon of contrasts.

If we look at the total amount of rainfall during the season, we got 736 mm. If we use that number to characterize the monsoon, it is way above the long-term average of around 600-650 mm...

...but take a closer look, just 3 days delivered nearly half of what Pune normally receives over the entire monsoon season. The rest of the season was almost dead.

A seasonal total can hide the real story.

As the monsoon season comes to end, attached is daily variation in Pune shivajinagar rain from 1june-30september.
Pune recorded 736.2mm rain this season and out of this half of rain (~53%) occurred in just 1 week (3-9July).
This shows highly skewed rainfall pattern.
