The summertime mei-yu–baiu rainband over East Asia displays considerable interannual variability. A singular value decomposition (SVD) analysis for interannual variability reveals that precipitation anomalies over the mei-yu–baiu region are accompanied by in situ anomalies of midtropospheric horizontal temperature advection. Anomalous warm (cool) advection causes increased (decreased) mei-yu–ba...

CONTEXT Hypothermia and frostbite injuries occur in cold weather activities and sporting events. EVIDENCE ACQUISITION A PubMed search was used to identify original research and review articles related to cold, frostbite, and hypothermia. Inclusion was based on their relevance to prevention and treatment of cold-related injuries in sports and outdoor activities. Dates of review articles were l...

Mustard (Brassica juncea L.) production in India suffers from aphid, Lipaphis erysimi (Kaltenbach), infestation considerably. Role of weather on the incidence and development of mustard aphids was assessed from experimental data from six north Indian locations. Aphid appearance and population build up was found to be regulated by temperature and time to attain peak population was relatively sho...

[1] Column-integrated moist static energy (MSE) budgets were calculated using daily data from three reanalyses (1998–2001) and ISCCP radiative cooling. The MSE export by the circulation was separated into vertical and horizontal MSE advection components in order to examine how observationally-derived vertical motion profiles affect gross moist stability calculations. In a 2000 km-wide region in...

A time integration scheme based on semi-Lagrangian advection and Laplace transform adjustment has been implemented in a baroclinic primitive equation model. The makes it possible to use large steps. However, errors arising from the semi-implicit increase with step size. In contrast, using remain relatively small for typical steps used advection. Numerical experiments confirm superior performanc...

The Weather Research and Forecasting model (WRF) is a simulating system developed for atmospheric weather prediction. WRF model is used for both operational as well as research purposes. The need for accurate weather and climate simulation to be carried out in shorter time is increasing day by day, which leads to the acceleration of existing Numerical Weather Prediction (NWP) system. This paper...

In this paper, the exponential B-spline functions are used for the numerical solution of the advection-diffusion equation. Two numerical examples related to pure advection in a finitely long channel and the distribution of an initial Gaussian pulse are employed to illustrate the accuracy and the efficiency of the method. Obtained results are compared with some early studies.

In Europe, the increase in temperatures caused by climate change has been particularly fast cold season. Although magnitude of this is relatively well known, less research done on how manifested different large-scale weather types, called regimes. For example, one could expect that patterns which air flowing from rapidly-warming Arctic would have warmed faster than other recent decades. Here we...
