The intensification of winter mid-latitude storms in the Southern Hemisphere [PDF]
, 2022 The strength of mid-latitude storm tracks shapes weather and climate phenomena in the extra-tropics, as these storm tracks control the daily to multi-decadal variability of precipitation, temperature and winds. By the end of this century, winter mid-latitude storms are projected to intensify in the Southern Hemisphere, with large consequences over the ...

The Adaptive Significance of Natural Genetic Variation in the DNA Damage Response of Drosophila melanogaster. [PDF]
, 2016 Despite decades of work, our understanding of the distribution of fitness effects of segregating genetic variants in natural populations remains largely incomplete. One form of selection that can maintain genetic variation is spatially varying selection,

Variation of Chromospheric Features as a Function of Latitude and Time using Ca-K Spectroheliograms for Solar Cycles 15-23: Implications for Meridional Flow [PDF]
, 2021 We have analysed the Ca-K images obtained at Kodaikanal Observatory as a function of latitude and time for the period of 1913 - 2004 covering the Solar Cycle 15 to 23. We have classified the chromospheric activity into plage, Enhanced Network (EN), Active Network (AN), and Quiet Network (QN) areas to differentiate between large strong active and small ...

The Swinburne Intermediate Latitude Pulsar Survey [PDF]
, 2001 We have conducted a survey of intermediate Galactic latitudes using the 13-beam 21-cm multibeam receiver of the Parkes 64-m radio telescope. The survey covered the region enclosed by 5 deg < |b| < 15 deg and -100 deg < l < 50 deg with 4,702 processed ...

Computational modes and grid imprinting on five quasi-uniform spherical C-grids [PDF]
, 2011 Currently, most operational forecasting models use latitude-longitude grids, whose convergence of meridians towards the poles limits parallel scaling. Quasi-uniform grids might avoid this limitation.

Speciation, Ecological Opportunity, and Latitude [PDF]
American Naturalist, 2015 Evolutionary hypotheses to explain the greater numbers of species in the tropics than the temperate zone include greater age and area, higher temperature and metabolic rates, and greater ecological opportunity.
