Diesel Cars banned in Oslo to fight air pollution
During one day this week, Oslo will ban diesel cars from the road. The ban went into effect on Tuesday on municipal roads based on a weather forecast that predict stabile weather with no wind. Diesel cars emit less carbon dioxide (CO2) than petrol fueled cars, but emit more nitrogen dioxide (NO2) and particulate matter (PM10). According to the institute of Public health in Norway, air ...

What is a long-range forecast?
In 2020, the global energy industry depends on high-quality weather forecasts for critical decision making like never before. Over recent decades the application of these forecasts has expanded exponentially due to the rapid growth of renewable energy and the liberalization of energy markets. Short-range forecasts are now an essential tool in the real-time management of wind and solar assets, ...

Climate change awareness in Africa and Asia `varies greatly`
For women living in rural areas of developing countries, levels of vulnerability to climate change and the capacity to adapt to its impacts varies greatly — with some even more resilient than men, three pilot studies in Africa and Asia has revealed. Researchers found that women's abilities to cope with various climate change impacts depend on factors such as social status; access to ...

Weather forecasting under extreme conditions in Russia - Megafon Russia - Case Study
The National Weather Service in Russia has about 1.800 weather stations which are distributed over the entire area of Russia. That's not enough to cover weather extremes everywhere. So the Russian National Weather Service wants to create a compression ratio of measurement points. In order to achieve the budget targets, our customer decided to buy our all-in-one sensor WS600-UMB. According to ...

Early warning system to forecast maximum temperature in drinking water distribution systems
Climate change poses new challenges in preventing the exceedance of the maximum allowed temperature in the drinking water distribution system (DWDS). The objective of this article is to evaluate the feasibility of forecasting the maximum temperature in the DWDS. Two options were analysed: (1) using the records of the last day as forecast for the coming 2 days and (2) using 2-day weather ...

NN-AirPol: a neural-networks-based method for air pollution evaluation and control
A method for air pollution evaluation and control, based on one of the most popular neural networks – the backpropagation algorithm, is proposed. After the backpropagation training, the neural network, based on weather forecasting data, determines the future concentration of critical air pollution indicators. Depending on these concentrations, relevant episode warnings and actions are activated. ...

Validation of a mass consistent flow model as part of a decision support system
In the context of real time (online) decision support systems for nuclear installations, atmospheric dispersion and deposition has to be calculated for a mesoscale area. Typically, the wind field in this area is influenced by topography. Therefore, simple Gaussian type modelling is not appropriate. Initiated and funded by the Bundesamt fur Strahlenschutz, simple (diagnostic mass consistent) flow ...

Will artificial intelligence replace the conventional weather forecasting system?
The 76th anniversary of the landing of Normandy was celebrated some days ago, a relevant historical event for the end of the Second World War and when meteorology played a crucial role. The landing took place exactly on June 6, 1944 due to the prior weather forecasts successfully conducte ...

Monitoring weather and climate from space
State of the art weather forecasting, which has become an essential part of everyday life in Europe, would be almost unthinkable without the reliable operational service delivered by Europe’s meteorological satellite organisation – EUMETSAT. The high-quality data and images are especially relevant in the context of severe weather situations and eather-related natural disasters. They are used by ...

Uncertainties in the meteorological input of the chemistry-transport models and some examples of their consequences
In this article, selected weather prediction model parameters, which are important for air pollution studies, were verified against measurements at two sounding stations in Finland. In 1996–1998, the short-time model-measurement differences were rather high. The friction velocity was on average overestimated by 30–70%, the mixing height during spring months was underestimated by up to 60%, 2 m ...

What is humidity?
Humidity is a natural phenomenon and is an amount of water vapour present in the atmosphere or in a gas. Water vapour itself is the gaseous state of water and is invisible to the human eye but we have all experienced how uncomfortable high humidity can make you feel. Humidity comes from water evaporating from lakes and oceans and since warmer water evaporates more quickly you find ...

Real time, high resolution regional weather and air quality forecasting system in West Macedonia, Greece
This paper presents an overview of the University of Western Macedonia's (UoWM) operational model for predicting the prevailing meteorological and air quality conditions on a high resolution (2 × 2 km²) scale. The MM5 – SMOKE – CMAQ has been suitably parameterised with respect to the particular geographical and climatic characteristics of the region of West Macedonia. The system is designed to ...

Environmental issues
Air pollution is now something we are all aware of and is often included alongside UV levels on weather forecasts. VOCs are themselves directly an air pollutant but also have secondary effects. When sunlight and heat react with VOCs, sulphur dioxide and nitrogen oxides (gasses released from many industrial process and vehicles) ozone is generated and smog is formed. ...

Distributed tree-based model predictive control on a drainage water system
Open water systems are one of the most externally influenced systems due to their size and continuous exposure to uncertain meteorological forces. The control of systems under uncertainty is, in general, a challenging problem. In this paper, we use a stochastic programming approach to control a drainage system in which the weather forecast is modeled as a disturbance tree. Each branch of the ...

Calculation of the far range atmospheric transport of radionuclides after the Fukushima accident with the atmospheric dispersion model MATCH of the JRODOS system
The paper presents estimates of the far-range atmospheric dispersion of radionuclides after the accident at Fukushima Daiichi Nuclear Power Plant (NPP), obtained using the long-range atmospheric dispersion model MATCH. Software tools were developed to run MATCH in the EU nuclear emergency response system JRODOS using freely available numerical weather prediction (NWP) data of the Global ...

Climate monitoring - meeting the challenge
Average global temperatures are on the increase, ice and snow cover is disappearing fast and sea levels are rising. In addition, severe weather situations are becoming more frequent and more extreme. There is clear evidence that the Earth’s atmosphere and oceans are warming: 11 of the 12 years in the period 1995-2006 were among the 12 warmest since 1850. Climate change is a reality and it is ...

A weather station for your camping holiday
A weather station in a vehicle? Might sound strange but when you go on a camping holiday, a weather station can be exactly what you need when making decisions about where to go next. Imagine you want to travel around in a camper or trailer. Those who like spending their holidays in more than one place instead of booking a package holiday and staying at the same hotel or hostel every night will ...
