Representation of atmospheric blocking in the new global non-hydrostatic weather prediction model ICON

open access: yesMeteorologische Zeitschrift, 2019
The correct depiction of atmospheric blocking still poses a key challenge for current numerical weather prediction (NWP) and climate models. This study evaluates the representation of blocking in the new global ICOsahedral Non-hydrostatic NWP and climate

Discovery of the brightest T dwarf in the northern hemisphere

open access: yes, 2006
We report the discovery of a bright (H=12.77) brown dwarf designated SIMP J013656.5+093347. The discovery was made as part of a near-infrared proper motion survey, SIMP (Sondage Infrarouge de Mouvement Propre), which uses proper motion and near-infrared ...

Comparative Experimental Efficiency of Solar Water Heating Systems With Enhanced Thermal Performance: A Review

open access: yesEnergy Science &Engineering, EarlyView.
This review presents a comparative analysis of experimental studies aimed at improving the thermal efficiency of solar water heating (SWH) systems. Various enhancement techniques, including nanofluids, phase change materials, optimized collector designs, and hybrid photovoltaic–thermal systems, are evaluated based on their impact on system performance ...

Simulations of the monthly mean atmosphere for February 1976 with the GISS model [PDF]

open access: yes
Monthly mean simulations of the global atmosphere were computed for February 1976 with the GISS model from observed initial conditions. In a replication experiment, two of these computations generated slightly different monthly mean states, apparently ...

Morpho‐Anatomical and HPTLC Investigations of Lysimachia nummularia L. (Primulaceae) Grown in Switzerland

open access: yesMicroscopy Research and Technique, EarlyView.
This research provides a complete morphoanatomical description of Lysimachia nummularia, as well as a HPTLC profile. Standard techniques of light and scanning electron microscopies, as well as standard techniques of HPTLC, were used. ABSTRACT Primulaceae are distributed all over the world, encompassing around 2590 species.

The 10-12-year atmospheric oscillation

open access: yesMeteorologische Zeitschrift, 1994
This paper summarizes the results of work which is based on the discovery by Labitzke (1982, 1987) of a 10-12-year oscillation in the arctic stratospheric temperature.

Variations of total ozone in the north polar region as seen by TOMS [PDF]

open access: yes
Data from the TOMS instrument has been used to follow the course of development of the Antarctic ozone springtime minimum since 1979. Addressed is the question of possible north polar region changes which might be deduced from the nine years of TOMS ...

How Well Is Surface Diurnal Temperature Range Represented by Observations at 2‐m Level

open access: yesInternational Journal of Climatology, EarlyView.
We demonstrate that geostationary satellites depict well the Diurnal Temperature Range (DTR) in the US but differ from information at 2 m level from model outputs. Upper: mean diurnal temperature range (DTR) using GOES‐E based land surface temperature (LST) for January (left) and July (right) during 2004–2009. Lower: mean diurnal temperature range (DTR)

Age and origin of enigmatic megaherbs from the subantarctic islands [PDF]

open access: yes, 2007
Biogeographic relationships in the southern hemisphere have puzzled biologists for the last two centuries. Once joined to form the supercontinent Gondwana, Africa, Antarctica, Australia, New Zealand and South America are widely separated by the Pacific ...
