Atmospheric conditions during two weather related aircraft incidents in Iceland and elements of the climatology of windstorms
Með aðstoð reiknilíkans, hefðbundinna veðurathugana og athugana úr flugvélum eru veðuraðstæður rannsakaðar þegar tvö flugatvik áttu sér stað á Íslandi. Reikningarnir gefa til kynna mikið upp- og niðurstreymi en þó ekki þau aftök sem í raun urðu. Niðurstöðurnar gefa vísbendingu um að eftir nokkru sé...
