In a local Cartesian system, a zonal jet has a form u(y) = u\(_0\) (1 - y\(^2\)/L\(^2\)), for \(-L \le y \le L\). Here, y is the meridional distance measured from the axis of the jet and is positive northward. The vertical component of vorticity of this flow at y=L/2 is \(\underline{\hspace{2cm}}\) s\(^{-1}\). Round off to 3 decimal places.
Suppose, because of the doubling of atmospheric CO\(_2\) concentration, an ocean water column receives an additional net energy input of 4 W/m\(^2\). If the entire water column of depth 1 km heats up uniformly, the water temperature will increase by 1 K in \(\underline{\hspace{1cm}}\) years (round off to the nearest integer).
Coral reefs are found primarily in tropical and subtropical shallow seaways. Which of the following statement(s) is/are correct?
Consider tropical high-level clouds and low-level stratus clouds with bases at 12 km and 1 km above the surface of the Earth, respectively. Which of the following statement(s) is/are correct?
Which of the following statement(s) is/are true with regard to the Hadley circulation?
The Ekman layer thickness, if turbulent diffusivity is 0.01 m\(^2\) s\(^{-1}\), is \(\underline{\hspace{2cm}}\) m. Take Coriolis parameter to be \( 10^{-4} \) s\(^{-1}\). Calculate to the nearest integer.
Which of the following statement(s) is/are correct in the context of Sverdrup transport?
Which of the following statement(s) is/are true about the ocean circulation?
CO\(_2\) concentration in the Earth's atmosphere is increasing because 50% of the annual anthropogenic emissions are retained in the atmosphere. If nations agree to reduce annual CO\(_2\) emissions by one Giga ton every year starting from 2021, then in which year will the CO\(_2\) concentration in the atmosphere stop rising due to anthropogenic emissions? Take the anthropogenic CO\(_2\) emissions in 2020 as 40 Giga tons.
The water vapour mixing ratio of an air parcel increases from 10 g kg\(^{-1}\) to 20 g kg\(^{-1}\) at a constant pressure of 1010 hPa and temperature of 300 K. The change in virtual temperature is \(\underline{\hspace{2cm}}\) K (to one decimal place).
The psychrometric equation, which is useful in measuring humidity, is derived assuming the following process(es).
