4. 9000 km

Correct Answer

Options:

1. Anticyclones that originate in the Arctic regions due to low insolation during winter.
2. Anticyclones that develop due to descent of air from above.
3. Anticyclones that follow two tracks, originating in Canada and Siberia respectively.
4. Anticyclones that die out upon entering tropical regions due to increased temperature.

Correct Answer

Options:

1. They are thermally induced due to low insolation in the Arctic regions.
2. They develop due to obstruction in the air circulation in the upper troposphere.
3. They are dynamically induced due to descent of air from above and consequent surface divergence.
4. They develop from the rear portion of temperate cyclones.

Correct Answer

Options:

1. Anticyclones that originate in N.W. Europe and the western part of the N. Pacific Ocean due to obstruction in the air circulation in the upper troposphere.
2. Anticyclones that follow two tracks, originating in Canada and Siberia respectively.
3. Anticyclones that die out upon entering tropical regions due to increased temperature.
4. Anticyclones that are thermally induced due to low insolation in the Arctic regions.

Correct Answer

Options:

1. Warm air rising over cold air resulting in a front called an ana front.
2. The region where surfaces of constant pressure intersect surfaces of constant density.
3. Temperate cyclones developed to the east of Canadian Rocky mountains.
4. The tem perate cyclones that develop in east Colorado state of the US

Correct Answer

Options:

1. The region where density does not vary along surfaces of constant pressure.
2. The sloping surface in a temperate cyclone along which cold air becomes aggressive and invades the warm air territory.
3. The air circulation having opposite conditions and characteristics of cyclone.
4. The region where surfaces of constant pressure intersect surfaces of constant density.

Correct Answer

Options:

1. The advancing cold air overtakes the warm front.
2. The resultant front when warm air becomes active and rises over cold air in a temperate cyclone.
3. Occurs when cold air behind the cold front is colder than the advancing cold air which is ahead of warm front.
4. None of the above.
