Ozone concentration in ground-level air layer in north-western Poland - The role of meteorological elements The research aimed at recognising time structure and variability of tropospheric ozone as a function of daytime and nocturnal meteorological conditions, particularly in the spring season (March-May), as well as finding a weather cluster at which the highest O3 concentration occurs. Ozone concentrations recorded every hour during the two years and data on five other meteorological elements: total solar radiation, air temperature, relative air humidity, atmospheric pressure, wind direction and speed provided the input data for the analysis. The data were collected at Widuchowa weather station, north-western Poland, near the Polish-German border. The highest ozone concentration was observed at daytime day, under conditions of eastern wind, low relative air humidity (about 35%), high values of total solar radiation (about 209 W·m-2), air temperature (17.0°C), atmospheric pressure (1016 hPa) and high wind speed (2.7 m·s-1). It is concluded that the magnitude of tropospheric ozone concentration recorded at Widuchowa is influenced by gaseous pollutants originating not only from the territory of Poland but also from Germany.

Along with the positive parts of the Moldovan climate - the warm period of the year, the mild winter, the abundance of light and heat - there are also some negative traits such as the high variability of the weather. The sudden changes in weather caused by the strong variation in the values of the main meteorological elements such as air temperature, precipitation, relative air humidity, nebulosity, and especially atmospheric pressure, adversely affect the health of a large number of people. When the body is virtually forced to suddenly pass from a temperature above 35°C to less than 17°C, it is instantly weakened. The immune system weakens and the body becomes vulnerable to viral infections. At the same time, the presence of nasal polyps, allergies, which affect the nasal mucosa and prolonged stress, increase the risk of developing viral infectionsThere are many people who accuse a state of acute fatigue, physical and mental asthenia, a state of continuous drowsiness and even depression, although they are properly resting.

<p>Investigations on correlation drops between near-ground atmospheric pressures measured at sea level and at higher altitudes on Italian volcanoes have been carried out. We looked for perturbations of the atmospheric pressure field driven by volcanic activity, but not excluding possible external triggers for the observed anomalies. Decorrelations between atmospheric pressures measured at Stromboli Island in stations located at different altitudes (years 2002-10) have been analysed and compared with data from other volcanic (Vesuvius) and non volcanic (Mt. Soro) orographic structures. We investigated as their possible triggers volcanic, meteorological and space weather parameters, with particular attention to Total Solar Irradiance (TSI), Kp index and Forbush decreases. Pressure decorrelations seems to be driven by astronomic cycles, with maxima in summer and minima in winter. A further contribution was found, seemingly assignable to TSI anomalies, with correlation minima occurring 12 hours after these but only during phases of high Sun activity. Moreover, during the same phases a main periodicity of about 27 days in pressure decorrelations was revealed by FFT analysis. This period is the same of the Sun Carrington rotation, expressing the periodic reappearance of sunspot groups on Sun’s surface. The strong similarity between recurrences of sunspot number and atmospheric pressure anomalies further supports the role of the former as a possible trigger for the latter.</p>

In the present study, we examined the role of different habitat components and their relationship with microhabitat use by three species of egret: Cocoi heron (Ardea cocoi), Great egret (Ardea alba), and Cattle egret (Bubulcus ibis), in wetlands of southern Brazil. Ardea alba and A. cocoi were not habitat-specific (e.g. vegetation cover and flooding level). Conversely, B. ibis was associated with drier microhabitats. Relative air humidity and air temperature were the main variables which correlated with the occurrence of these species and supported the plasticity of B. ibis and its predominance in drier habitats.

Objective: to analyze the influence of different meteorological conditions: relative air humidity, atmospheric pressure, precipitation on the incidence of development of AF paroxysms. Material and methods. The study involved 259 patients with AF paroxysms who were admitted into the Cardiology ward of Gomel City Clinical Hospital of Emergency Medical Care during the period from November 2015 to January 2016. Results. We have determined the incidence of development of AF paroxysms depending on such weather conditions as atmospheric pressure, relative air humidity, cloudiness, and precipitation. Conclusion. Meteorological conditions have a direct effect on the occurrence of AF paroxysms. The determined risk factors in this case are: high relative humidity, fall of temperature and harsh precipitation and changes in atmospheric pressure. Also, the aggravating factor in the development of AF paroxysms was age of patients over 56 and a combination of coronary heart disease and hypertension.

The differences of air temperature and relative air humidity in wheat, rape and maize canopies at three heights (ground level, effective canopy height and 2 meters above the soil surface), and their comparison with the temperature values of the nearest standard climatological station at the height of 2 meters were studied. The microclimatic data were obtained at the field trial station of the Mendel University in Brno in the Žabčice municipality (South Moravia) in the canopies of winter wheat, winter rape and maize and from the standard climatological station located immediately next to the canopies. It was found, that wheat, rape and maize canopies microclimate differed significantly from those of their surrounding environments. The temperature was usually lower in the ground level and effective height in the wheat and rape stands, air humidity was usually higher in these crops. On the other hand, maize canopies had diverse air temperature values during the studied period.

We studied the influence of weather conditions (air temperature, absolute and relative air humidity, atmospheric pressure, wind speed and geomagnetic activity) on the epidemic process of COVID-19 in Sumy that is a city in north-eastern Ukraine for the period 4.05.2020-22.03.2021. The study was carried out using nonparametric Kruskal-Wallis dispersive analysis. The obtained results show that all meteorological factors affect the COVID-19 incidence rate. The air temperature, absolute humidity and atmospheric pressure are the most important meteorological factors influencing COVID-19 epidemic process
