#6. TRS occurs over Indian seas in:
Tropical cyclones over Indian seas generally occur between 5°N and 15°N latitude.
#7. In the Bay of Bengal during the months of Jul, August, Monsoon Depression form:
During Jul-Aug, monsoon depressions mostly form over the central Bay of Bengal.
#8. In a monsoon depression maximum weather occurs in:
Maximum weather is observed in the SE sector of monsoon depressions.
#9. During re-curvature maximum weather in a monsoon depression occur in:
After re-curvature, maximum weather is in the SE sector.
#10. On whatever compass course the cyclone is approached, strong winds from the port indicate that the centre lies somewhere:
Strong winds from port indicate the cyclone center is to port side.
#11. The well developed extra tropical cyclonic storm is composed of two main frontal systems and an occluded front, which varies in extent:
Extra-tropical storms usually have a low with a warm front radiating southwards followed by a cold front.
#12. Cyclonic storms are confined almost entirely to the:
Tropical cyclones are restricted to tropical latitudes.
#13. The weather expected in a well developed cyclonic storm is:
A well-developed cyclonic storm brings stormy weather.
#14. After entering land the Cyclones gradually die down
Cyclones weaken on land due to loss of energy from warm sea water.
#15. The most dangerous part of the cyclone is:
The eye wall has the strongest winds and heaviest rains.
#16. No cyclonic storm forms:
Cyclones do not form exactly at the equator due to lack of Coriolis force.
#17. Average life of a tropical cyclone in India is:
Typically, tropical cyclones last 6-8 days over Indian seas.
#18. Cyclonic storms in India are mostly of intensity:
Indian cyclones are mostly severe in intensity.
#19. Eye of a cyclonic storm is surrounded by:
The eye is surrounded by the eye wall, composed of wall clouds.
#20. Cyclonic storms in Indian region are less intense because:
Indian cyclones are less intense as they have short sea travel, limiting energy intake.
#21. Surge is sudden strengthening of wind in the ______ air mass:
Surge occurs when the wind suddenly strengthens in a different air mass.
#22. Surge and Shear Line are features of _______ monsoon:
These features appear during vigorous monsoon periods.
#23. Peninsular discontinuity occurs along:
Peninsular discontinuity is observed along the east coast.
#24. Peninsular discontinuity occurs during:
This discontinuity occurs in the pre-monsoon season.
#25. Surge is also:
Surge is related to velocity convergence in the wind field.
#26. In a depression the wind speed is:
Monsoon depressions have wind speeds less than 17 kt.
#27. In a cyclonic storm the wind speed is:
Cyclonic storms have wind speeds around 28-33 kt.
#28. A monsoon depression slopes ______ with height:
Monsoon depressions slope SE with height.
#29. Average life of a monsoon depression is:
Monsoon depressions usually last 3-5 days.
#30. Monsoon depressions move faster over:
Monsoon depressions move faster over plains than hills or rivers.
#31. For formation of a cyclonic storm sea surface temperature should be:
Cyclonic storms require sea surface temperature above 26°C.
#32. In a extra tropical cyclone family there are 3 - 4 cyclonic storms or depressions, one to the ___ of the other:
They are typically aligned SE of each other.
#33. In TRS the central pressure is about:
Tropical cyclones have central pressures around 900–1000 hPa.
#34. TRS develop over:
Tropical cyclones develop over warm sea waters.
#35. TRS develop over ______ deg Lat:
TRS mostly occur between 5–15°N latitude.
#36. In TRS pressure gradient is very steep up to a radius of:
TRS pressure gradients are steep up to about 50 km radius.
#37. Extra Tropical Storms originate in:
Extra-tropical cyclones originate along the polar front.
#38. Extra-tropical Storms generally move in the direction:
They typically move from west to east.
#39. A Tropical Cyclone moves ______ in a day:
Tropical cyclones typically move 300–500 km per day.
#40. A Tropical Cyclonic Storm has outer storm area of about:
The outer storm area usually exceeds 400 km in diameter.
