The Tibetan Plateau (TP), known as the third pole of the Earth, has snow cover with intraseasonal to decadal variability that affects weather and climate both inside and outside the TP. However, the factors that generate the TP snow cover (TPSC) anomalies at the intraseasonal time-scale are unclear. This report reveals the influence of the Madden‒Julian oscillation (MJO), which is the most domi...

Invertebrates collected in the Republic of Karelia 2016 from nests pied flycatcher Ficedula hypoleuca (Pallas, 1764) are analyzed and 516 specimens invertebrates identified. The vast majority these Hymenoptera (ants genus Camponotus) – 46.6% various beetles (Coleoptera) 46.37%. An annotated list 38 species beetle 22 families is presented. fauna studied European mixed includes both nidicolous fr...

Traditional regression models, including generalized linear mixed focus on understanding the deterministic factors that affect mean of a response variable. Many biological studies seek to understand non-deterministic patterns in variance or dispersion phenotypic ecological We describe new R package, dalmatian, provides methods for fitting double hierarchical models incorporating fixed and rando...

Global cloud/cloud system-resolving models are perceived to perform well in the prediction of the Madden-Julian Oscillation (MJO), a huge eastward -propagating atmospheric pulse that dominates intraseasonal variation of the tropics and affects the entire globe. However, owing to model complexity, detailed analysis is limited by computational power. Here we carry out a simulation series using a ...

A Madden-Julian Oscillation (MJO) is a massive weather event consisting of deep convection coupled with atmospheric circulation, moving slowly eastward over the Indian and Pacific Oceans. Despite its enormous influence on many weather and climate systems worldwide, it has proven very difficult to simulate an MJO because of assumptions about cumulus clouds in global meteorological models. Using ...

The processes that lead to changes in the propagation and maintenance of the Madden-Julian Oscillation (MJO) as a response to increasing CO2 are examined by analyzing moist static energy budget of the MJO in a series of NASA GISS model simulations. It is found changes in MJO propagation is dominated by several key processes. Horizontal moisture advection, a key process for MJO propagation, is f...

Detecting chaos and estimating the limit of prediction time in heavy-noise environments is an important and challenging task in many areas of science and engineering. An important first step toward this goal is to reduce noise in the signals. Two major types of methods for reducing noise in chaotic signals are chaos-based approaches and wavelet shrinkage. When noise is strong, chaos-based appro...
