| Abstract [eng] |
Winter severity evaluation has been a difficult task to crack for climatologists for decades. This task becomes even more burdensome once this evaluation needs to represent a certain application or task effectiveness, like winter road maintenance. Thus, the AccumulatedWinter Season Severity Index (AWSSI) has been calculated in hopes to get an accurate and objective index for winter road maintenance task difficulty assessment. After initial evaluation, it was noted, thatAWSSI performed a lot better than previously usedindices, thusit was decided to improve the methodology and make it a bit more suitable for Lithuanian climate, more applicable to Lithuanian RWIS network and less dependent to climate change.A several methodology changes were performed and an adaptation of AWSSI was created.The resulting adapted AWSSI is a great tool to determine winter severity for road maintenance. It was shownthat the index correlates well with performed winter road maintenance tasks and material usage. Thus, it can be used in various fields, e.g., long-term forecasts and planning, and currently is being used to determine a part of worker wages. |
