Weather-station data coverage, quality, and completeness across British Columbia, Canada, degrade outside of population centers and as one goes back in time. This data paucity motivates the search for the best reanalysis to serve as a climatological reference dataset. This study focuses on how well reanalyses represent 2-m temperature (T2M). System...

This study evaluates how well reanalyses represent daily and multiday accumulated precipitation (hereinafter daily PCP) over British Columbia, Canada (Part I evaluated 2-m temperature). Reanalyses are compared with observations from 66 meteorological stations distributed over the complex terrain of British Columbia, separated into climate regions b...

In this work we review some of the theoretical efforts and experimental evidences related to Dark matter and Dark energy problems in the universe. These dilemmas show us how incomplete our knowledge of gravity is, and how our concepts about the universe must at least be revised. Mainly, on the Wilkinson Microwave Anisotropy Probe (WMAP) fifth year,...

The cosmological constant problem is examined within the context of the covariant brane-world gravity, based on Nash’s embedding theorem for Riemannian geometries. We show that the vacuum structure of the brane-world is more complex than General Relativity’s because it involves extrinsic elements, in specific, the extrinsic curvature. In other word...

Forecasters are increasingly overwhelmed by the firehose of data available to them. It’s imperative that they have tools that help them efficiently and accurately distill important information from this data. This study presents an improved extreme forecast index for temperature and precipitation for situational awareness. First, temperature and pr...

The extreme weather events of greatest concern in British Columbia include heavy precipitation, drought, unseasonably hot and cold periods, and wind storms. These weather events directly impact the general population as well as British Columbia’s primary utility company, BC Hydro. To gauge the severity of an extreme weather event, a historical data...

We study the effect of the extrinsic curvature on the rotation curves within the context of brane-world, in a 5-d bulk with constant curvature. The covariant equations of motion for the brane-world are applied to determine the modified Newtonian potential approximation and the velocity curve. We consider a static disk galaxy which is composed only...

In this paper, we deal with the evolution of physics and maths, and how one is intrinsically connected to the other. Euclid and his book Elements, and the importance of the fifth postulate for geometry led to the discovery of non-Euclidean geometries. We point out how these geometries play an essential role in immersion theory and Nash's theorem, a...

Apesar dos modelos de Branas-mundo terem recebido atenção considerável nos últimos anos por fornecerem várias opções à física contemporânea, seus mecanismos não são completamente entendidos ou apropriadamente justificados. Tendo em vista tal dificuldade, neste trabalho fornecemos uma contribuição pedagógica dirigida especialmente aos alunos de pós-...

Although brane-world models have gained considerable attention in the last years for providing several options for contemporary physics, their mechanisms are not completely understood or properly justified. Taking into account such difficulty, in this work we provide a pedagogical contribution, written especially for physics graduate students, and...
