Which type of precipitation is formed when warm air rises due to intense surface heating?
(a)
Drizzle consists of droplets less than 0.5 mm with intensity:
< 2.5 mm/hr
2.5–7.5 mm/hr
> 7.5 mm/hr
< 1 mm/hr
The instrument that produces a mass curve is:
Tipping bucket
Weighing bucket
Symons gauge

What is the unit of intensity of rainfall?
(a)
Rain gauge density for hilly region (IS:4987–1968):
1 per 520 km²
1 per 260–390 km²
1 per 130 km²
1 per 1000 km²
Frontal precipitation occurs when:
Hot air moves downslope
Warm air moves downwards
One air mass overrides another
Air rises by convection

Weighing bucket
Tipping bucket
Float type
Symons rain gauge

True
False
Float-type rain gauges do not produce mass curves.
True
False
