Solution:
The features of anti-cyclonic conditions are as follows:
Anticyclones are the opposite of cyclones, with high pressure in the centre and the isobars far apart. Hence, Statement 1 is NOT correct.
The pressure gradient is gentle and winds are light.
Anti-cyclones normally herald fine weather.
Skies are clear.
The air is calm and temperatures are high in summer but cold in winter. Hence, Statement 2 is correct.
In winter intense cooling of the lower atmosphere may result in thick fogs.
Anti-cyclonic conditions may last for days or weeks and then fade out quietly.
