Intensywność procesów eolicznych na Mierzei Kurońskiej (?koniec XX?-?początek XXI wieku?)

Intensity of aeolian processes on Curonian Spit (?the end of the XX century?-?beginning the XXI century?)

Summary: This article analyses the development of moving sand dunes on the Curonian Spit over the last 180 years. The research of dune dynamics was conducted using topographical maps from 19?th and 20?th centuries, large-scale thematic maps and digital databases. Precise measurements with electronic tachymeters ELTA 500 and Trimble GeoXT 6000 were also performed. The deflation relief forms were mapped using high-precision GPS devices. The analysis of historical evolution of shifting dunes and areas of drifting change from the 19?th to the 21?st century is presented in this paper. The current evolution of deflation relief forms were studied in detail from 1999 to 2014. The development of such forms was associated with perennial change of local climatic factors (?wind, rainfall, temperature?). Special attention was paid to the wind regime. The Juodkrante - Pervalka segment of deflation relief forms was researched and described in detail?: hollows, pits, deflation gullies, passages, yardangs and deflation-accumulation complexes. Four separate areas with deflation-accumulation processes of different intensity were distinguished in the Juodkrante - Pervalka segment, their morphological characteristics and morphographical features were described.

Słowa kluczowe (w języku angielskim): aeolian deflation and accumulation, wind regime, morphology of aeolian forms, dynamics of aeolian forms
