Surface layer structure for ten categories of land surfaces of the Indian region with instrumented Mini Boundary Layer Mast Network (MBLM-Net) establishment during PRWONAM

Surface layer structure of nine Convective events at seven locations of durations 2 to 6 days are discussed. During the event at BIT, Ranchi with continuous rain for 4 days and peak rainfall of 20 mm h−1, maximum dip in pressure by ∼10 hPa, strong signature in soil temperature at depths up to 100 cm, drastic reduction in incoming SW radiative flux to < ∼100 W m−2 and the incoming LW radiative flux approaching near zero values, maximum dip in air temperature by ∼5° C, increase in relative humidity by ∼30% at its peak and in wind speed with the peak at ∼5.9 m s−1are observed.
