Finnish snow research articles published in a special issue
Finnish snow research articles published in a special issue
Snow research and services enable weather predictions and safe air traffic, for example. The special issue of the Geophysica-journal contains information on the Finnish snow expertise the whole society benefits from.
Short term forecasting – or nowcasting – of snow events is required for safe and sound airport operation. The paper by Elena Saltikoff et al. shows what kind of mathematical techniques can be used for the purpose.
In unpopulated areas, automated continuous snow observations are important for weather prediction, climate modelling and interpretation of remote sensing observations. Leena Leppänen, Anna Kontu and Jouni Pulliainen have compared the manual and automated snow measurements in Sodankylä, Finland, and found automatic measurements to be accurate and usable for snow depth, snow water equivalent (SWE) and snow temperature.
Extreme weather events, such as sea-effect snowfall, can have severe impacts on infrastructure and human safety. A good understanding of such heavy sea-effect snowfalls in the present climate is essential if we want to assess the probability of their occurrence and intensity in the future. A record-breaking snowfall of 73 cm (31 mm as liquid water) fell in less than a day in Merikarvia, Finland, on 8 January 2016. Taru Olsson et al. investigated the case with an ERA5 reanalysis, the Global Navigation Satellite System (GNSS), and the numerical weather prediction model HARMONIE, using weather radar information as a reference.
Terhikki Manninen and Emmihenna Jääskeläinen used an albedo model to simulate various components of the forest scattering and showed how boreal forests can affect the snow albedo in Finland. The effect appeared largest at high latitudes, where the midday sun elevation is low and the canopy small and sparse. This information is essential for weather predictions and climate modeling approaches.
Arctic collaboration issues were included
The special issue of Geophysica also includes an article by Juhani Damski, the Director General of the Finnish Meteorological Institute, where he emphasizes the importance of Arctic and Nordic collaboration. Outi Meinander and Ali Nadir Arslan explain in their article the backgrounds for the Pyry100 snow seminar, part of the Finland 100 Project on the centenary of Finland's independence at the Prime Minister's Office, as well as for the European Union funded snow Action coordinated by Finland. Johanna Ekman comments on Finland's Chairmanship of the Arctic Council 2017-2019 and its working groups.
The Finland100 special issue of the Geophysica-journal contains almost 100 pages. It appeared on-line during 2018 and as printed in January 2019. The articles are based on the presentations given at the Pyry-seminar on 1 November 2017, organized by the Finnish Meteorological Institute. The authors are researchers from Finland, Estonia, Austria and Germany. The reviewers were from Finland and abroad. The editor of the special issue was Outi Meinander, researcher at the Finnish Meteorological Institute. Geophysica is a peer-reviewed Open Access journal of the Geophysical Society of Finland, published since 1935. The editor-in-chief is professor emeritus Kimmo Kahma.
