Which of following correct regarding a warm anticyclone It increases in intensity with increasing altitude. there are two main types of anticyclone a cold warm anticyclone cold anticyclones form typically over polar climates here temperatures are very low the air often cold dense an inversion tends to develop at low altitudes with anticyclones this prevents clouds from building any further if this so any cumulus which does form during daytime will quickly stop growing spread into a layer of stratocumulus then disperse when night comes at night when temperatures drop below freezing frosts are very likely to form warm anticyclones form mainly over tropical or sub tropical climates where temperatures are often warm both at day night with these highs air subsiding at quite a depth through troposphere this tends to hold back restrict any cloud formation if any cloud do form they will often be erratic well broken these being mainly cumulus stratocumulus.

Question 142-11
In north atlantic you can often see a series of depressions located in a row and travelling from west to east these depressions Are normally generated at polar front. Easa 2014 polar front depressions which develop due to polar front cause bad weather conditions from surface to tropopause move from atlantic towards europe (their tracks are variable) regions located south of each depression experience frontal weather. Question 142-12
What are typical weather conditions in an area with a flat pressure pattern in summer Generally fine weather possibly thunderstorms in afternoon or evening. Easa 2014 during summer in centre of a stationary high pressure zone ( = flat pressure pattern) we have light or no wind thunderstorms may occur in summer months in afternoon or evening due to convective activity (the land warms causing convective lifting = cb). Question 142-13
What change in pressure will occur at point b during next hour 392 Approximately constant pressure. Easa 2014 without a scale we can't tell if cold front will pass through this position during next hour but question statement during next hour not 'in one hour' spacing of isobars at point b in front of cold front are same therefore pressure will not change during next hour in about one a half hours we can expect to see a drop in temperature pressure.
