In this study we examined the response of soil CO2 pulses to rainfall size and pre-rain soil moisture conditions in a semiarid grassland.
Rainfall size had a larger impact on the response than pre-rain soil moisture conditions.
The rain drop size during actual rainfall varies between 0.8 and 5 mm in diameter and the underwater bubble sizes can vary from 0.5 mm to 10 mm in diameter.
The data are analysed to study the nature of rain drop size distribution (DSD) in this region.
Rain drop size distribution (DSD) was measured at four places in Southern India {Thiruvananthapuram, Kochi, Munnar and Sriharikota (SHAR)} using a Joss Waldvogel (JW) impact type disdrometer.
To examine the influence of water addition and temperature on nitrogen fixation and denitrification rates, we conducted a full factorial design of biocrust color (dark, light), simulated rain event size (0.05, 0.2, 0.6, 1 cm), and temperature (10, 20, 30, 40°C) in the laboratory.
For sandy soils, the rain garden size should equal about 10-20% of the total drainage area, while for very clayey soils, aim to make your rain garden equal to 50-60% of the total drainage area.
A frontal system pushing through the area caused the outbreak of severe weather, which included torrential rain, baseball-size hail and strong, gusty winds.
Numerical prediction of this phenomenon requires knowledge of wind speed, rain drop sizes and rain fall intensity among others.
Studies have indicated that the rain drop sizes are a function of the rainfall intensity.
