Is the Indian summer present in Romania? The first part of the study refers to the occurrence of the Indian summer events in Romania, over the 1961-2019 period. The second part analyses the Indian summer event recorded in Romania in October 2019. The datasets used for the first part were daily maximum and minimum temperatures recorded in the past 59 years at 23 climatological weather stations, divided into 6 regions. Regarding the methodology, first step was to determine the annual and seasonal occurrence of the first frost for each weather station, and then the presence of the warm spells (WSs), based on the percentile threshold method. So, we could determine WSs with different types of intensity (using the 90th, 95th, 98th percentile), and durations. For the Indian summer event recorded between 12 and 28 October 2019, daily maximum temperatures from 157 weather stations were compared to absolute maximum temperatures over the period 1961-2018. Synoptic conditions were determined using weather charts at sea level pressure, geopotential height and temperature of 925, 850, 700 and 500 hPa. The main finding is: Indian summer events are frequent in the Carpathians and in the Northern, Central and the Western regions of Romania, especially in November, followed by October; no matter the intensity, short duration events have high number of cases, and severe and extremely severe events were registered in the past 20 years; the Indian summer event from October 2019 was influenced by synoptic and local conditions, as well. Overall the Indian summer is not present in Romania every year, but it is more frequent and intense in the last 20 years. [ABSTRACT FROM AUTHOR]

This paper provides a case study of the dangerous meteorological phenomena which took place in the interval 18 - 20 May 2008, in the Western part of Romania. During this period, the Southern and South-Eastern regions of Europe entered the influence of a very hot air mass of tropical origin. By contrast, a cold, humid and unstable air mass pressed on from the North-West of Europe, carried along by the dorsal of the Greenland Anticyclone. Upon the contact of these two air masses characterised by significant thermobaric differences, in the unstable conditions created, a number of dangerous meteorological phenomena took place, manifested in the West of the country in the form of intense lightning, torrential showers, hail and squall. The effects of these dangerous phenomena were numerous: hundreds of hectares of crops compromised; houses, bridges and roads destroyed by floods, hail and wind; trees brought down by squall; localities suffered shortages in electricity or drinking water; buildings caught fire; livestock and domestic animals perished etc. In the following days the dangerous meteorological phenomena caused massive destruction almost everywhere else in the country.

The article discusses the climate report for the year 2015 published by the intergovernmental organization the World Meteorological Organization on the occasion of World Meteorological Day and mentions topics such as the temperature for the year 2015 and the effects of global warming.

The article announces that the World Meteorological Organization (WMO) will celebrate the World Meteorological Day on March 23, 2015 with the theme "Climate: Understand to Act." Topics cited include the global average air temperature over land and sea during 2014, as well as the climatic and hydrological risk phenomena that occurred in 2014. Effort of the international community to prepare to make decisions and measures to tackle climate change is noted.

The author reflects on the issue of climate change as the World Meteorological Organization (WMO) celebrates the 2014 World Meteorological Day. Particular focus is given to problems facing today's young people, as well as the hazards posed by climate change to their lives. Topics discussed include 2013 as one of the warmest years in modern history, meteorological and hydrological risk phenomena that occurred around the world in 2013, and the issue of greenhouse gas mitigation.

The article focuses on the celebration of the World Meteorological Day (WMD) by the World Meteorological Organization (WMO) on March 23, 2013. It mentions the launch of the World Weather Watch (WWW) program by WMO and notes that it includes Global Telecommunication System (GTS) and Global Data Processing and Forecast System (GDPFS). The impact of weather extremes is also discussed.

The article offers information on the 2012 World Meteorological Day, held on March 23, 2012. The subject proposed for this year's celebration is "Powering our future with weather, climate and water." The World Meteorological Society published a booklet dedicated to this event, which contains topics on climate and health, disaster risk reduction, transport trade and tourism, energy and climate, sustainable cities, and powering and empowering the future.
