See comment on PNAS paper by Tata Institute of Social Sciences
Spurious linkages between extreme temperatures and farmer suicides

A recent paper, published by the PNAS (Proceedings of the National Academy of
Sciences of the United States) and authored by Tamma A. Carleton, titled “Climate
Change and Agricultural Suicides in India” claims that “temperature during India’s
main agricultural growing season has a strong positive effect on annual suicide rates.”

Hello All,

as some of you may be aware, we have been involved in
building a climate modelling framework that can be used
entirely from Python.

I'm happy to inform you all about the first release of CliMT.
This version of CliMT is capable of running as a simplified
GCM, with a spectral dynamical core. The components
currently available in CliMT are suitable for research use.

Please do play around, and I am happy to receive any

Documentation, including installation instructions, are
available at:

The code is available at:

which contains many examples that you can adapt for
your own needs.

Land-use and land cover change (LULCC) can have significant biophysical impacts on regional precipitation, including monsoon rainfall. Using global simulations with and without LULCC from 5 general circulation models (GCM), under the Representative Concentration Pathway (RCP) 8.5 scenario, we find that future LULCC significantly reduce monsoon precipitation in at least 4 (out of 8) monsoon regions. While monsoon rainfalls are likely to intensify under future global warming, we estimate that biophysical effects of LULCC substantially weaken future projections of [UTF-8?]monsoons’ rainfall by 9% (Indian region), 12% (East Asian), 32% (South African) and 41% (North African) relative to the changes in RCP8.5, with an average of ~30% for projections across the global monsoon regions. A similar strong contribution is found for biophysical effects of past LULCC to monsoon rainfall changes since the preindustrial period. Rather than remote effects, local land-atmosphere interactions, implying a decrease in evapotranspiration, soil-moisture and clouds along with more anticyclonic conditions, could explain this future reduction in monsoon rainfall.

CAOS PhD Thesis Defence

Title: Temporal Persistence and Spatial Coherence of Tropical Rainfall

Speaker: Ram Ratan

Date: December 30, 2016 (Friday)

Time: 4:00PM

Venue: CAOS Seminar Hall


This work focuses on documenting the multiscale nature of the temporal
persistence and spatial coherence of tropical rainfall.  The first two
parts utilise satellite-retrieved rainfall  at multiple space and time
resolutions,   and   the   third   part  assesses   the   ability   of
state-of-the-art  coupled models  to  reproduce some  of the  observed

In  the  first part  of  the  study,  which  focuses on  the  temporal
persistence  of rain,  we  analyze the  Tropical Rainfall  Measurement
Mission (TRMM)  satellite-based observations  to compare  and contrast
wet and dry spell characteristics over the tropics (30S-30N).  Defining
a wet (dry) spell as the  number of consecutive rainy (nonrainy) days,
we find  that the distributions  of wet spells (independent  of spatial
resolution) exhibit  universality in the following  sense.  While both
ocean and land regions with high seasonal rainfall accumulation (humid
regions) show a predominance of 2-4 day wet spells, those regions with
low seasonal rainfall accumulation (arid  regions) exhibit a wet spell
duration distribution that is  essentially exponential in nature, with
a peak  at 1  day. The behaviour  that we observed  for wet  spells is
reversed for  dry spell distributions. The  total rainfall accumulated
in each wet  spell has also been  analyzed, and we find that the major
contribution to  seasonal rainfall  for arid  regions comes  from very
short length wet spells; however, for humid regions, this contribution
comes from wet spells of duration as  long as 30 days. We also explore
the role  of chance  in determining the  2-4 day mode  as well  as the
influence of organized convection in separating reality from chance.

The second part deals with the spatial coherence of tropical rain.  We
take two different  approaches, namely, a global and  local view.  The
global view attempts to quantify  the conventional view of rain, i.e.,
the dominance of the intertropical  convergence zone (ITCZ), while the
local view tries to  answer the question: if it rains,  how far is the
influence  felt   in  zonal   and  meridional  directions?    In  both
approaches, the  classical e-folding length for  spatial decorrelation
is used as  a measure of spatial coherence.  The  major finding in the
global  view approach  is that,  at short  timescales of  accumulation
(daily to  pentad to even  monthly), rain  over the Equator  shows the
most  dominant  zonal scale.   It  is  only  at larger  timescales  of
accumulation (seasonal or annual) that the dominance of ITCZ around 7N
is evident.  The local view quantifies  the dominance of the zonal
scale  in the  tropical ocean  convergence zones,  with an  anisotropy
value (ratio of zonal to meridional scales) of 3-4.  Over land, on the
other  hand,  the  zonal  and  meridional  scales  are  comparable  in
magnitude,  suggesting that  rain tends  to be  mostly isotropic  over
continental regions.  This latter  finding holds true, irrespective of
the  spatial  and temporal  resolutions  at  which rain  is  observed.
Interestingly, the anisotropy over ocean, while invariant with spatial
resolution, is found  to be a function of temporal  resolution: from a
value  of 3-4  at daily  timescale, it  decreases to  around 1.5-2  at
3-hourly resolution.

The final part  analyses a few models from the  suite of Coupled Model
Intercomparison Project  (CMIP5) models, to evaluate  their ability to
reproduce some of  these aforementioned features.  For  all the strong
biases that  models are known to  have, some of the  observed features
(e.g., 2-4  day mode  in wet  spells, isotropic  rain over  ocean) are
remarkably well reproduced.
