Flowering out of sync: Climate change alters the reproductive phenology of Terminalia paniculata in the Western Ghats of India

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Understanding how climate change impacts the plant life cycle is critical for maintaining biodiversity and ecosystem services. Our findings suggest that Terminalia paniculata Roth, a common tropical deciduous tree species in the Western Ghats, is now flowering and fruiting at more scattered times than it used to in the past.

Using a causal effect network approach to quantify the impact of ENSO teleconnections on summer monsoon precipitation over the Himalayas and key regional circulations

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
We quantified the causal effect (CE) of linkages between four monthly climate indices ENSO, SMHP, RWC, and MHC for 1940–2022 with a time lag of one month. The results show CE values from (1) ENSO to SMHP of −0.33$$ -0.33 $$ to −0.44$$ -0.44 $$ (i.e., a one standard deviation (SD) increase in ENSO causes a decrease in SMHP of −0.33$$ -0.33 $$ to −0.44$$

The revival of Himalayan papermaking: historical, social-cultural and economic aspects

open access: yesZ Badań nad Książką i Księgozbiorami Historycznymi, 2020
We normally hardly notice the mass-produced paper products that pass through our hands on a daily basis, which we then recycle. In fact it has recently been predicted that books printed on paper will be replaced by digital formats. However, paper endures

A unified theory of granularity, vagueness and approximation [PDF]

open access: yes, 2001
: We propose a view of vagueness as a semantic property of names and predicates. All entities are crisp, on this semantic view, but there are, for each vague name, multiple portions of reality that are equally good candidates for being its referent, and,

On the origin of the North Pacific arcs [PDF]

open access: yes, 2004
We present a new hypothesis that relates global plate tectonics to the formation of marginal basins, island arcs, spreading ridges and arc-shaped mountain belts around the North Pacific Ocean.

Indian and African monsoons: Trajectories and interactions

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
The catch basin of marine air particles of the Indian monsoon is the tropical Indian ocean, whilst that of the African monsoon is the east tropical Atlantic. However, the oscillations induced by the monsoonal interactions favour particle exchange between the two basins. These transitions are abrupt in the presence of stochastic resonance. The monsoonal

Are northeast and western Himalayas earthquake dynamics better "organized" than Central Himalayas: An artificial neural network approach

open access: yesGeofísica Internacional, 2007
Los Himalayas entre los 20 y 38 grados de latitud N y los 70 a 98 grados de longitud E están entre las regiones más activas y vulnerables a los temblores en el mundo.

The non‐hydrostatic option of the ECMWF global weather forecast model: Improvements for kilometre‐scale modelling

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
This study presents improvements to the non‐hydrostatic version of the European Centre for Medium‐Range Weather Forecasts (ECMWF) Integrated Forecasting System (IFS), enabling stable global simulations at 1.4‐km resolution. A systematic comparison with the hydrostatic version at resolutions from 9 to 1.4 km shows that non‐hydrostatic effects emerge in ...

Ecophysiological Plasticity and Cold Stress Adaptation in Himalayan Alpine Herbs: Bistorta affinis and Sibbaldia procumbens

open access: yesPlants, 2019
Plants have evolved several metabolic pathways as a response to environmental stressors such as low temperatures. In this perspective, it is paramount to highlight physiological mechanisms of plant responses to altitudinal gradients as a proxy to ...
