“…Also, the variability in the depth of the land plume offshore could be a manifestation of the diurnal change in the PBL over land and the travel distance of the daytime and nighttime air masses [see also Ansmann et al, 2001]. Height of the typical daytime PBL over Indian subcontinent during this period is of the order of 2000 m [Raman et al, 1990] and the nocturnal boundary layer about 300 m. Thus there is a distinct difference in the land air mass characteristics that travel over the ocean between day and night. This feature is discussed further with the presentation of numerical modeling analysis and airborne lidar data.…”

“…Earlier studies have generally shown that the depth of the diurnal convective boundary layer (CBL) is of the order of 1000 m, while that of the nocturnal stable boundary layer (SBL) is of the order of 100 m [1]. However, studies on the ABL under special geographical conditions and extreme climatic conditions during the past 10 years have gradually changed the past point of view [2][3][4][5]. For example, Takemi's study [6] on ABL characteristics of the arid region of the Hexi Corridor, Northwest China, inferred that the depth of the CBL is more than 4 km from conventional meteorological sounding data of characteristics of the residual layer.…”

“…Previous studies and observations have pointed out the ABL heights can be as much as 5 km in lower latitudes such as in India under special climatic conditions (Raman et al 1990;Garratt 1992). Normally, the ABL height is less than 2-3 km in the middle latitudes but varies in different regions.…”
