Statement I : Anticyclone, which is a high pressure wind system, does not bring about significant change in weather condition. Statement II : The outward movement of wind from the high pressure center keeps limited scope for weather disturbance.

Statement I is correct as anticyclones are high-pressure systems characterized by light winds and stable, settled weather conditions with minimal cloud formation [c1][t3]. They typically herald fine weather, clear skies, and calm air, lasting for days or weeks without significant change [c1][t1]. Statement II provides the correct explanation for this stability. In an anticyclone, air descends (subsides) from the upper troposphere, creating high pressure at the surface [c2][c4]. This sinking air compresses and warms, which inhibits the formation of clouds and precipitation [t4][t5]. At the surface, the air moves outward (diverges) from the high-pressure center [c4][t1]. This combination of subsidence and surface divergence prevents the vertical uplift necessary for atmospheric disturbances, thereby maintaining stable weather conditions [c2][t6]. Thus, the outward movement and sinking motion are the physical mechanisms that limit weather disturbances.
