On 13 February 2020, The Guardian, followed by many other newspapers and websites, published the news that on 9 Antarctic air temperatures rose to about 20.75 ?C in a base logged at Seymour Island. This value has not yet been validated WMO (World Meteorological Organization), but it is first time an extreme temperature was registered these locations. recorded have often described as “abnormal a...

This work presents the spatial distribution and temporal variability of lightning activity over continental territory Chile by means Thunderstorms days (Td), on basis 7 years (2012–2018) measurement from World Wide Lightning Location Network (WWLLN). Td are obtained separately for 15 geopolitical regions Chile, reporting higher in northeastern region country with 85 thunderstorms per year. Thes...

In recent years, introduction of alternative energy sources such as solar energy is expected. Solar heat energy utilization systems are rapidly gaining acceptance as one of the best solutions to be an alternative energy source. However, thermal energy collection is influenced by solar radiation and weather conditions. In order to control a solar heat energy utilization system as accurate as pos...

The new generation of weather observatory satellites, namely Global Precipitation Measurement (GPM) constellation satellites, is the lead observatory of the 10 highly advanced earth orbiting weather research satellites. Indeed, GPM is the first satellite that has been designed to measure light rain and snowfall, in addition to heavy tropical rainfall. This work compares the final run of the Int...

Climate change implies a statistically significant in the long-term mean state or characteristics of variability climate elements. It can be caused by natural and/or anthropogenic factors. Recent global warming is often cited as an example human-induced change. Global refers to increasing trend average surface temperature Earth, defined annual ocean, usually depth 30-100 cm, and air above land ...

A medical-meteorological weather assessment using hybrid spatial classification of synoptic and meteorological data was done. Empirical models for assessment as well as for forecast of medical-meteorological weather type at the seaside climatic zone in Palanga were developed. It was based on the data of meteofactors (atmospheric pressure, relative humidity, temperature, oxygen density in atmosp...

A total lunar eclipse is conjectured to have influence on the physical conditions of an environmental area, particularly on the brightness of the sky. The phenomenon might also be relevant on weather parameters change on Earth, such as temperature, humidity and pressure, though a straightforward correlation is not easy to establish. This work mainly aims at measuring the brightness of the sky a...

Abstract The overall aim of this study is to enable the traceable International System Units (SI) determination column-integrated aerosol optical depth (AOD) retrieved from passive remote sensing atmosphere using SI-traceable direct solar spectral irradiance measurements. A precision filter radiometer that measures for retrieval AOD has been characterized and calibrated at state-of-the-art cali...

The aim of the study was to characterise Artemisia pollen season types according to weather conditions in Wrocław (south-western Poland) in the years 2002-2011. Over the period analysed, the start date of the pollen season (determined by the 95 % method) ranged from 10 July 2002 to 28 July 2010. The start date of the pollen season can be determined by using Crop Heat Units (CHUs). During the pe...
