- 37. These nuclei comes from sea salt or combustion products of sulfurous and nitrous acids
- 44. Due to higher saturation capacity around the droplets, some water evaporates
- 45. While due to low saturation capacity around the ice crystals vapors condense and ice crystal size increases
- 57. In the hot day, the ground surface gets heated, causing the warmer air to lift up
- 59. The vertical air currents develop tremendous velocities the vapors condensed and Convective precipitation occurs
- 66. A front may be warm front or cold front depending upon whether there is active or passive accent of warm air mass over cold air mass
- 91. The chart is rotated by a spring-driven or electric clock at speeds of 1 revolution in 6, 9, 12, 24, or 192 hours
- 92. The rain gauge chart is a record of the accumulated of rainfall for the selected time interval
- 94. It weighs rain or snow which falls into a bucket, set on a platform with a spring or lever balance
- 99. Bucket then tips over, emptying collected water into total container and continues to collect rainfall in other container
- 108. Blowing wind may tilt the rains from vertical which thus brings less rain catch in the gauge
- 109. Vertical upward air currents may impact upward acceleration to precipitation thus brings less rain catch in gauge
- 112. Tipping of bucket may be affected due to rusting or accumulation of dust on pivot
- 119. Recording rain gauge also gives intensity of rainfall at any time, while non-recording gauge gives only total rainfall for time interval
- 131. Index station ≈ surrounding stations around interpolation station whose data is used to calculate the missing rainfall data
- 134. And Pi is the precipitation at ith station
- 138. And Pi is the precipitation at ith station
- 139. Nx and Ni are the normal annual precipitation value for station x and ith respectively
- 141. Nx and N1 , N2 and N3 are the normal annual precipitation value for station x and 1,2 and 3rd station respectively
