Mesoscale Bora flow and mountain pressure drag
The paper analyses the Bora periods on the basis of 10-minute microbarographic measurements (ALPEX 50P, March-April 1982) and the corresponding surface pressure drag values. In the cases with pressure drag with larger negative values than -1.3⋅10-3 Nm-3 the Bora was very strong over the entire North...

| description | The paper analyses the Bora periods on the basis of 10-minute microbarographic measurements (ALPEX 50P, March-April 1982) and the corresponding surface pressure drag values. In the cases with pressure drag with larger negative values than -1.3⋅10-3 Nm-3 the Bora was very strong over the entire Northern Adriatic coast. It is shown that pressure drag is highly correlated with the cross-mountain pressure differences which confirms the results from PYREX where such a simple relationship was found for the Pyrenees. The results suggest the possibility of application of the linear regression method in drag estimation for periods for which microbarographic data are not available. Mesoscale analysis of ALPEX Bora cases emphasize the large isentropic slope. The strongest gradient in the geopotential height field over the Dinaric Alps coincided with the strongest Bora. |
