An unsaturated moist air parcel undergoes adiabatic ascent in the atmosphere without mixing with surrounding air. Air is so clean that there is no possibility for heterogeneous nucleation. Which one of the following plots depicts the vertical variation of water vapor pressure (shown as continuous line) and saturation water vapor pressure (shown as dotted/dashed line) of the parcel?

A fluid is in solid body rotation in a cylindrical container of radius $R$ rotating with an angular velocity $\Omega = (0, 0, \Omega)$. The circulation per unit area around a circular loop in the horizontal plane of radius $r$ ($r<R$), whose center coincides with the axis of rotation is

Consider a layer of atmosphere where temperature increases with height. If the concentration of a vertically well-mixed greenhouse gas suddenly increases in this layer, then an immediate consequence is that:

Which of the following statement(s) is/are true about northern hemisphere tropical cyclones?

Which of the following feature(s) characterize the seasonal mean flow in the upper troposphere near 200 hPa level over the Tibetan Plateau during the boreal summer?

Tropical cyclones usually do not form close to the Equator primarily because

The dry bulb temperature and relative humidity of air inside a storage chamber are 37°C and 50%, respectively. The saturation pressure of water vapour at 37°C and barometric pressure are 6.28 kPa and 101.32 kPa, respectively. The humidity ratio of air inside the chamber is _________ \text{ kg water / kg dry air}. (Round off to three decimal places.)
