Introduction Biometeorological circumstances have a big in fluence on all traffic participants, especially reflexes, moving co ordi nation and perception ability. With a lower attention and drivers' and pedestrians' concentration, there was a larger amount of pedestrian trauma in certain biometeorological phases. Objective The aim of this study was to establish the correlation between pedestrian trauma and biometeorological phases. Methods The comparative analysis of everyday biometeorological phases for the city of Kragujevac determined by RHMI and the evidence of knocked-down pedestrians from the Kragujevac traffic police for the period 2003-2008. Results There were 6,127 accidents, with 696 knocked pedestrians in 666 (10.87%) accidents. Most of them happened in 2003 (135), and the fewest in 2005 (90). Most accidents were during December (74), the fewest were in June (46). The fewest accidents were during 04-05-06 hour interval (by 2), most during 13-14 hours (61). There were 374 males and 349 females. Most of the males (by 60) were 0-10 and 11-20 years old, most of the females (74) were 11-20 years old. There were 443 pedestrians who suffered slight body injuries (112 were 11-20), 225 suffered heavy and 28 had lethal injuries (most over 70). As provokers, the pedestrians suffered because of improper crossing roads (185), while as a casualties, they suffered due to speeding of vechicles (285). Most accidents happened in biometeorological phases 4 (168) and 9 (151), the fewest in phase 10 (4). Conclussion Statistical analysis shows a significant correlation between pedestrians' accidents and biometeorological phases, when the most accidents occurred during penetrations of cold fronts, while there was a sudden switch of weather conditions from warm-dry to cold-wet weather.

Introduction Biometeorological circumstances have great influence on all traffic participants, especially on reflexes, movement coordination and perception ability, increasing the number of accidents. Motocyclists and bicyclists are specific participants in traffic, so their traumatism has its own special characteristics. Objective The aim of this study was to establish biometeoro logical influence on motorcyclists and bicyclists accidents. Methods Comparative analysis of everyday biometeorological phases for the city of Kragujevac determinated by the Republic Hydrometeorological Service of Serbia and motorcyclists and bicyclists accident evidence received from Kragujevac traffic police for the period 2004-2008. Results There were 5,180 traffic accidents in this period, with 180 accidents in which 77 motorcyclists and 116 bicyclists were knocked down. Most of the accidents were in 2008 (53) and the least in 2005 (28). Most accidents occurred during August (28) and between 19.00 and 20.00 hours (18). There were no accidents during January, between 04.00 and 06.00 hours. There were 85% accidents in the urban area. Most of 169 males were aged 16-20 and 21-25 years (20 and 21). Most of 24 females (6) were aged 11-15 years. Those who caused the accident mostly sustained injuries due to improper speed limit (31), while the victims due to the disrespect of street-crossing priorities (32). Forty-one motorcyclists and 85 bicyclists suffered mild body injuries. Thirty-one motorcyclists and 27 bicyclist suffered severe injuries. Five motorcyclists and four bicyclists ended lethally. Most accidents happened in biometeorological phases 9 (63), 4 (32) and 1 (31). Conclusion Statistical analysis showed a significant correlation between accidents and biometeorological phases, with most accidents occurring during stabile warm weather and rapid penetrations of cold fronts, and with a sudden switch of weather conditions.

In this study, a comprehensive analysis of long-term trends of the Koshava wind during the period between 1949 and 2010 is carried out. Koshava is a strong wind that blows from southeast quadrant over Serbia, Bulgaria and Romania. The Siberian high and West-Mediterranean cyclones, together with the orography of the eastern Balkan, are the main drivers of the Koshava wind. The trend analyses are performed on wind data sets from five synoptic weather stations, all situated in the region where the Koshava wind is fully developed. Koshava wind speeds are divided into two categories: (1) all wind speeds and (2) wind speeds above 5ms-1. Two homogeneity tests are used to inspect the quality of wind speed and wind direction time series. The Mann-Kendall test and Sen's slope estimator are used to analyze trends of the Koshava wind speeds and the annual number of days with the Koshava wind. Statistically significant negative trends of the Koshava wind speeds and wind activity are observed at all five weather stations and are more pronounced for wind speeds above 5ms-1. The negative trends of the Koshava wind are mostly related to the changes in the synoptic circulation, temperature and weakening of the Siberian high and West-Mediterranean cyclones. It is shown that the observed decline of the Koshava wind has a significant impact on reducing the wind energy potential in the region. © 2014 Royal Meteorological Society. Source

The annual and seasonal trends of mean, maximum, and minimum temperatures were analyzed on the territory of Vojvodina, north Serbia. We used observed, quality controlled, homogenized, and spatially averaged data from 9 meteorological stations during two periods: 1949-2013 and 1979-2013. Positive trends were found in 29 out of the 30 analyzed time series using a linear tendency (trend) equation, while negative trends were found in only 1 case. After the application of the classical Mann-Kendall (MK) test, statistically significant positive trends were confirmed in 15 series, while in remaining cases, statistically significant trends were not confirmed. After applying the modified MK test, positive trends were found in 26 series, and 4 cases were with no trend. We find that significant positive trends are dominated during the year, spring and summer; and they are most numerous in the time series of monthly mean temperatures. In accordance with the behavior of analyzed trends, the increase of temperatures is dominant in Vojvodina. © 2016, Hungarian Meteorological Service. All rights reserved. Source

Aim To determine influence of biometeorological phases on stroke incidence according to age and gender of patients, place of residence, days in a week, months in a year, type of stroke, additional diagnosis. Methodology Comparative analysis of the data on stroke patients (according to age, months, days, place of residence, age, sex, stroke type, additional diagnosis and number of hospitalization days) obtained by examining the records of discharge and admission of patients in the Department of Neurology of Kragujevac and everyday biometeorological phases obtained from the Republic Hydrometeorological Service of Serbia (RHMS of Serbia), for the following years: 2003, 2004, 2007, 2008 and 2009 in Kragujevac. Results 4,700 patients diagnosed with stroke were hospitalized in the observed period. The highest number of strokes was noted in 2003 (1,030), the lowest in 2008 (851). The highest number of strokes was in March (444) and the lowest in February (351).The most frequent days were Mondays (805), and the least frequent Sundays (495). Three fifths of patients were from urban areas and the rest of them were from rural areas. Out of this number 2,382 (50.7%) were males and 2.318 (49.3%) were females, of which 1.847 (77.6%) males and 1,894 (81.7%) females were over 70 years old. The average number of hospitalization days was 12.29 days, and most patients were in hospital for less than 10 days (2101 patients). 4,130 (87.9%) patients were diagnosed with thromboembolism, 422 (9.0%) with intracerebral hemorrhage and 148 (3.2%) with subarachnoid hemorrhage. As an additional diagnosis 1,946 (41.4%) patients had hypertension, 867(18.6%) had heart insufficiency and 15.40% had diabetes. Most strokes with significant correlation were in biometheorological phases 9 and 4 (1,227 and 1,010 strokes) and the least were in phase 10 (29). As a daily average, the highest number of strokes was in phase 8 (2.76/ day), the lowest in phase 2 (2.33/day). Conclusion Biometeorological phases have a great influence on stroke incidence, especially in phases with stable sunny weather and sudden impact of weather fronts, with sudden weather changes, with average incidence in the phase of foggy weather.
