Polar Science is gaining increased importance in Climate Change studies because of the profound influence Polar Climatology has on the Global Climate. Research shows that Antarctica seems to be warming around the edges and cooling at the center at the same time. East Antarctica is climatologically colder than west Antarctica because of its higher elevation.
A short term characterization of wind and the temperature over Maitri is attempted in this paper. Maximum and Minimum temperatures showed a tendency to decrease with winter contributing the most to the change. The Wind Directions were predominantly South-South-Easterly in summer and autumn and South-Easterly in winter and spring, with katabatic winds showing the maximum frequency in autumn. The wind speeds were found to be most variable in winter. Greater contributions to the wind chill temperatures were found from the winds, with the tendency for change being more prominent in the transition seasons.
