Features of transformation of organic matter in the forest  reserves of the Crimea

open access: yesЮг России: экология, развитие, 2019
Aim. The aim of the research was to identify the migration of ash elements and  nitrogen in the leaf litter‐soil  system for forest biogeocenoses of the Crimean  mountains, taking into account the effect of the pyrogenic factor on pine forests of  the ...

How consistently do ensemble prediction systems represent the growth of atmospheric uncertainty?

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
Spread‐based diagnostics calculated for 12 ensemble prediction systems are compared to understand the consistency with which they represent atmospheric uncertainty growth. Good correlation between all these systems is found in the extratropics for a lead time range from 48 hr to between 96 hr and 192 hr.

Stratospheric and tropospheric seasonality and its implications for observation requirements in numerical weather prediction

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
Daily time series of zonal‐mean zonal wind (m·s−1) at 10 hPa and 60° N from 1950 to 2021 from the ERA5 reanalysis. This shows huge variability in some seasons and very little in others. We provide evidence that high‐level observations, radiosonde and satellite, are more important during the extended winter season with its very large variability ...

Dispersion and distribution of trace and ore elements in the polymetalic vein- type Chah-Mesi ore deposit, north of Shahre-Babak

open access: yesJournal of Economic Geology, 2020
Introduction The Chah-Mesi polymetallic vein-type ore deposit, located 40 km north of Shahre-Babak city and 1.5 km southwest of Miduk porphyry copper deposit, is situated in the Dehaj-Sarduieh belt as a part of the Urumieh–Dokhtar magmatic Arc (UDMA) (

Intensity dependence of El Niño and La Niña evolution and mixed‐layer heat‐budget processes

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
El Niño–Southern Oscillation (ENSO) intensity modulates the spatial, temporal, and dynamical evolution of events strongly. El Niño SST anomalies shift westward with decreasing intensity, while La Niña anomalies remain spatially fixed. Stronger events initiate earlier and persist longer than weak events.

Karkonosze MTS. National Park soils acidification in relation to vertical zonality and land usability

open access: yes, 1998
This paper presents results of investigations on mountain soils reaction and acidity. Soils samples have been taken from Karkonosze Mts. National Park area. The aim of the work was to compare an influence of meadow and forest sites and climatic condition

A multimodel intercomparison study of variable‐resolution global models with grid refinement over the Arctic and Antarctic

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
We document the protocol and first results from the first ever coordinated multimodel variable‐resolution experiment set with refinement over the polar regions. We find that the refinement generally yields model‐dependent effects. The most consistent improvement is an amelioration of the upper‐level cold bias in the polar regions that translates into ...

Characterization of synoptic environment for mesoscale convective systems over South Korea using ERA5 reanalysis data

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
In this study, the synoptic conditions for modes of mesoscale convective systems (MCSs) in South Korea are generalized based on composite analysis. The preferred precipitation region, synoptic patterns, moisture transport, sea surface temperature and thermodynamic and dynamic instabilities are characterized according to four modes: convective cells (CC)

Exploiting Aeolus winds in a regional numerical weather prediction model

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
Aeolus measured winds have proven to be beneficial for global models. However, demonstrating positive impact for limited‐area models has been a challenge so far. For the first time, we have demonstrated a statistically significant positive impact of Aeolus winds in a limited‐area model by using the 4DVar data assimilation technique and the most recent ...

Average vertical and zonal F region plasma drifts over Jicamarca

open access: yesJournal of Geophysical Research: Space Physics, 1991
The seasonal averages of the equatorial F region vertical and zonal plasma drifts are determined using extensive incoherent scatter radar observations from Jicamarca during 1968–1988. The late afternoon and nighttime vertical and zonal drifts are strongly dependent on the 10.7‐cm solar flux.
