Today, we're discussing the cold weather season in India, which spans from mid-November to February. Can anyone tell me what happens to the temperatures during this time?

Exactly! The average temperature in Chennai can be around 25°C, while in the northern plains, it can drop to around 10°C. This temperature gradient is very important. Remember: 'Cold in the North, Warm in the South' – that's a great memory peg!

Good question! Yes, nights can be quite cold and frost is common in northern areas. So, during winter, you might often hear people talk about the chilly nights!

Correct! These winds blow from land to sea, keeping most areas dry. However, Tamil Nadu receives some winter rainfall because the winds shift and hit the coast. We can remember this with the phrase 'Northeast Winds, Tamil Rain'.

Great question! Cyclonic disturbances originate over the Mediterranean and can bring crucial winter rains to the northern plains, although they aren’t very plentiful. They are vital for 'rabi' crops, which farmers grow in winter. 'Cyclones Bring Crops' can help us recall this!

Now, let's look at temperature variations. Why do you think we have different temperatures in places like Drass and Thiruvananthapuram?

You're right! Drass can fall as low as -45°C, while Thiruvananthapuram stays around 22°C. The geographical features create these vast differences.

In places like the Thar Desert, for example, temperatures can soar during the day but drop significantly at night. So, there's a broad range in diurnal temperatures. Remember: 'Desert Heat, Night Chill'.

Finally, let’s connect winter weather to farming. How might the cold and dry conditions affect crops?

Exactly! The colder temperatures and light rains are great for crops like wheat and barley. It’s essential they get adequate moisture during this period. Let’s remember: 'Cold Weather, Strong Crops'.

Without sufficient winter rainfall, crops could suffer, leading to food shortages. This highlights the importance of the winter cyclones we discussed earlier!
