Solar Geoengineering Effects on Malaria Transmission Risk in South Asia Under G6sulfur Scenario

International Journal of Climatology, EarlyView.
Comparison of EIR (unit: No of infected bites per person per day) for each considered country in South Asia, under the considered scenarios, averaged over the period 2020–2090. A regression equation is shown for each country (for Bhutan EIRG = 0.1690 × 10−10 EIRS + 0.5968 × 10−12) to illustrate the projected trend.

Tomographic reconstruction of atmospheric gravity wave parameters from airglow observations [PDF]

Atmospheric Measurement Techniques, 2017
Gravity waves (GWs) play an important role in the dynamics of the mesosphere and lower thermosphere (MLT). Therefore, global observations of GWs in the MLT region are of particular interest.

Decadal Changes of UV Aerosol Optical Depth in Hobart, Australia Measured With a Brewer MKIII: Relationship to Bushfire Events and Climate Indices

International Journal of Climatology, EarlyView.
Monthly average aerosol optical depth at 320 nm obtained with a Brewer MKIII spectrophotometer for Hobart, Australia (42.8806° S, 147.3250° E) over a 21‐year period. There is a linear trend of 15.4% per decade. There are 9 months when the average aerosol optical depth exceeds twice the monthly standard deviation.

Three-dimensional tomographic reconstruction of atmospheric gravity waves in the mesosphere and lower thermosphere (MLT) [PDF]

Atmospheric Measurement Techniques, 2018
Gravity waves (GWs) have been intensively studied over recent decades because of their dominant role in the dynamics of the mesosphere and lower thermosphere (MLT).

Reaction Rate Coefficients and Adduct Formation in the Cl Atom + (E)‐CF3CF2CH=CHCF2CF3 Reaction

International Journal of Chemical Kinetics, EarlyView.
ABSTRACT In this work, rate coefficients for the Cl‐atom + (E)‐CF3CF2CH═CHCF2CF3 (HFO‐153‐10mczz, F22E) gas‐phase reaction were measured as a function of temperature and pressure, k(243–323 K, 50–300 Torr), using a pulsed laser photolysis‐resonance fluorescence (PLP‐RF) technique.

Moist bias in the Pacific upper troposphere and lower stratosphere (UTLS) in climate models affects regional circulation patterns [PDF]

Atmospheric Chemistry and Physics
Water vapour in the upper troposphere and lower stratosphere (UTLS) is a key radiative agent and a crucial factor in the Earth's climate system. Here, we investigate a common regional moist bias in the Pacific UTLS during Northern Hemisphere summer in ...

Fractional Moment Theory for Anomalous Transport: A Unified Framework for Lévy Flights, Fractals, and Complex Dynamical Systems

Mathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT We develop a unified mathematical framework extending classical moment theory from discrete integer orders to a continuous spectrum of real orders f>0$$ f>0 $$, providing a systematic statistical characterization of complex systems exhibiting power‐law behavior.

First tomographic observations of gravity waves by the infrared limb imager GLORIA [PDF]

Atmospheric Chemistry and Physics, 2017
Atmospheric gravity waves are a major cause of uncertainty in atmosphere general circulation models. This uncertainty affects regional climate projections and seasonal weather predictions.

Performance evaluation of regional weather predictions with the Model for Prediction Across Scales – Atmosphere (MPAS‐A) over the Maritime Continent

Quarterly Journal of the Royal Meteorological Society, EarlyView.
As part of the ongoing efforts to develop next‐generation forecasting systems at the Meteorological Service Singapore, this study presents the setup and evaluation of the SINGV_NG(MPAS) system. Overall, the SINGV_NG(MPAS) system outperforms European Centre for Medium‐Range Weather Forecasts (ECMWF) deterministic forecasts in capturing heavy rainfall ...
