Voorbeelden van zonal

• Negative blocking indicates that the zonal mass flux is greater over the obstacle than it is far upstream.

• Membership was confined to the regional commissioner, rural development officer, zonal rural development officer, regional technical officers and the administrative secretary.

• My informants also insisted that zonal commanders, political officials and civilians organised relations between civilians and guerrillas differently, particularly during early phases of the war.

• In our model, energy is transported across zonal boundaries by winds and by diffusive heat flow in the 50 m deep wind-mixed ocean layer.

• The stability criterion and the characteristic oscillation frequency of the zonal flow are determined in terms of the spectra of turbulent fluctuations.

• This gives a better idea of the importance of each zone than the presentation of zonal averages as such.

• General relations are derived for the forcing of a mean zonal flow in a damped rotating barotropic system through the action of weak eddies.

• The threshold and growth rate of the instability as well as the optimal spatial scale of zonal flow are obtained.
