Studies on the Vertical Structure of Horizontal Wind Variability in the Surface Boundary Layer Over Sriharikota

considered as being within the mesoand microclimatology scales, then approximately one third of the specialist climatology courses at that time were concerned with this spatial scale. Assuming that this state of affairs still prevails, it is surprising that this progress report represents the first in this journal specifically on this theme. Despite its popularity at undergraduate level, it is not a field in which large amounts of literature have appeared. Books on the subject are occasional, such as Yoshino (1975), Lee (1978), Landsberg (1981), Atkinson (1981), Barry (1981), Rosenberg (1983), Jones (1983), Grace (1983), Oke (1986) and Romanova (1986). However, one of the most popular texts, Boundary layer climates (Oke, 1987), has recently been published in a second edition, 10 years after its first appearance. The same format is retained with additions and updating to confirm the stability of the subject matter. Articles are much more numerous and cover

Micro- and mesoclimatology

Long-term (45 years) diversified surface meteorological records from Thumba Equatorial Rocket Launching Station (TERLS), India, were collected and analysed to study the long-term changes in the overall climatology, climatology pertained to a particular observational time, mean daily climatology in temperature, inter-annual variability in temperature, interannual variability in surface pressure, and rainfall for the main Indian seasons—South West and North East monsoons and inter-annual mean monthly anomaly structure in temperature. Results on various analyses show strong and vivid features contributed by climate change for this South Peninsular Indian Arabian Sea Coastal Station, and this paper may be a first time venture which discusses climate change imparted perturbations in several meteorological parameters in different time domains, like a specific time, daily, monthly, and interannually over a station. Being a coastal rocket launching station, climatic change information is crucial for long-term planning of its facilities as well as for various rocket range operational demands.

Climatic Variation at Thumba Equatorial Rocket Launching Station, India

Sea-breeze features over Sriharikota, India

Agricultural planning as well as many operations depend considerably on the success of dry and over wet spells. A first order Markov chain model has been, utilized to study the initial, and conditional probabilities of weekly rainfall, In terms of dry and wet spells during 1954-1984 at four locations In south coastal Andhra Pradesh The patterns of dry weeks show considerable spatial and temporal variations. The information is useful to agricultural planners in determining the suitable crop or variety for a particular location and in adopting the appropriate agricultural practices.
