First, an automated 35-dBZ reflectivity threshold-based storm area detection algorithm is used to derive initial individual convective cells from the base level radar reflectivity. Those detected cells are used as a basis combined with convective available potential energy (CAPE) values from ERA5 reanalysis to find thresholds for a severe convective storm in Estonia. A severe convective storm is defined as an area with radar reflectivity at least 51 dBZ and CAPE at least 80 J\/kg. Verification of those severe convective storm areas with lightning data reveals a good correlation on various temporal scales from hourly to yearly distributions. The probability of a severe convective storm day in the study area during the summer period is 45%, and the probability of a thunderstorm day is 54%. Jenkinson Collison\u2019 circulation types are calculated from ERA5 reanalysis to find the probability of a severe convective storm depending on the circulation direction and the representativeness of the investigated period by comparing it against 1979\u20132019. The prevailing airflow direction is from SW and W, whereas the probability of the convective storm to be severe is in the case of SE and S airflow. Finally, the spatial distribution of the severe convective storms shows that the yearly mean number of severe convective days for the 100 km2 grid cell is mostly between 3 and 8 in the distance up to 150 km from radar. Severe convective storms are most frequent in W and SW parts of continental Estonia.<\/jats:p>","DOI":"10.3390\/rs13112178","type":"journal-article","created":{"date-parts":[[2021,6,2]],"date-time":"2021-06-02T21:23:41Z","timestamp":1622669021000},"page":"2178","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Climatology of Convective Storms in Estonia from Radar Data and Severe Convective Environments"],"prefix":"10.3390","volume":"13","author":[{"given":"Tanel","family":"Voormansik","sequence":"first","affiliation":[{"name":"Institute of Physics, University of Tartu, 50411 Tartu, Estonia"},{"name":"Numerical Modeling Department, Estonian Environment Agency, 10616 Tallinn, Estonia"}]},{"given":"Tuule","family":"M\u00fc\u00fcrsepp","sequence":"additional","affiliation":[{"name":"Institute of Physics, University of Tartu, 50411 Tartu, Estonia"},{"name":"Department of Earth Sciences, ETH Zurich, 8092 Zurich, Switzerland"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3537-3005","authenticated-orcid":false,"given":"Piia","family":"Post","sequence":"additional","affiliation":[{"name":"Institute of Physics, University of Tartu, 50411 Tartu, Estonia"}]}],"member":"1968","published-online":{"date-parts":[[2021,6,2]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"104789","DOI":"10.1016\/j.atmosres.2019.104789","article-title":"Geographical Distribution of Extreme Deep and Intense Convective Storms on Earth","volume":"235","author":"Wu","year":"2020","journal-title":"Atmos.
