The job of observational meteorology is to produce knowledge of the condition of the atmosphere at a desired future time. This problem has not been solved for the scientific weather forecaster in even the most felicitous circumstances. Two gaps are especially noticeable. Firstly, the only weather stations reporting daily are on the land. On the sea, which constitutes four fifths of the earth’s ...

Since discovering the shrinking politician sound bite, researchers have shown that TV news grew more journalist-centered since the 1960s. To explore how far journalistic authority extends, this study turns to the weather. We examine local coverage weekday mornings on three local stations before a national convention. Close qualitative reading, supplemented by content coding, compares weather rh...

Understanding the trend of localized severe weather under the changing climate is of great significance but remains challenging which is at least partially due to the lack of persistent and homogeneous severe weather observations at climate scales while the detailed physical processes of severe weather cannot be resolved in global climate models. Based on continuous and coherent severe weather ...

Weather derivatives are contingent claims with payoff based on a pre-specified weather index. Firms exposed to weather risk can transfer it to financial markets via weather derivatives. We develop a utility-based model for pricing baskets of weather derivatives under default risk on the issuer side in over-the-counter markets. In our model, agents maximise the expected utility of their terminal...

Floods, the most common and hazardous natural event in Sri Lanka, are mainly caused by excessive rainfall received during monsoons resulting from development of low-pressure systems in the Bay of Bengal. From 2004 to 2014, Sri Lanka faced 23 flood occurrences with over 500 lives being lost and 9 million people affected. These floods caused an economic loss of USD 1 billion, reveals data availab...

Modelling daily wind speed data by using the two parameter Weibull distribution for ten selected weather stations in Sri Lanka is presented. The daily wind speed data measured by the Department of Meteorology at the heights of 6m-15m during the years 2001 and 2004 were used in this work. The annual variation of the fitted Weibull parameters, the shape parameter k and the scale parameter c range...

Apple scab, Venturia inaequalis, is the most serious fungal disease of apple in Romania. The fungus attacks foliage, blossoms and fruits by defoliating trees and rendering fruit unmarketable. In addition, to cultivated apple, apple scab also attacks flowering crabapple, mountain ash and firethorn.. A simple system for apple growers to monitor environmental weather data (temperature and leaf wet...

For the proper planning and operation of any electric power system, it is essential to have a reliable software tool that allows for accurate short-term forecasting consumption. Temperature one most important drivers energy consumption selecting appropriate weather station or combination stations crucial improving accuracy. In this study, we propose an algorithm determine optimal selection base...

Stochastic weather generators are used in different studies which often require long series of daily weather data for risk assessment. They can produce synthetic daily time series of any length. Any generator should be tested to ensure that the synthetic data is proper for the purposes for which it is to be used. The main objective of this paper is to test a stochastic weather generator, LARS-W...
