How does the Hopkin Bioclimatic Law define the delay in crop production and morphological development relative to geographic movement?
How does the Hopkin Bioclimatic Law define the delay in crop production and morphological development relative to geographic movement?
- A delay of *twelve days* for each degree of latitude, one degree of longitude, and five meters of altitude when moving eastward and westward.
- A delay of *five days* for each degree of latitude, one degree of longitude, and twelve meters of altitude when moving southward and downward.
- A delay of *one day* for each degree of latitude, five degrees of longitude, and twelve meters of altitude when moving northward and upward.
- A delay of *four days* for each degree of latitude, five degrees of longitude, and twelve meters of altitude when moving northward and upward. (correct)
Considering the dynamics of monsoon winds, why do they blow from cold to warm regions?
Considering the dynamics of monsoon winds, why do they blow from cold to warm regions?
- Cold air contracts and descends, increasing pressure and pushing air towards warmer, low-pressure zones.
- Warm air expands and rises, creating a void that draws in cooler air from surrounding regions. (correct)
- Cold air is heavier and takes up more space than warm air, creating a pressure gradient that draws wind towards warmer regions.
- Warm air is denser and displaces cold air, initiating wind movement towards warmer areas.
How does the differential heating of land and sea influence the behavior of monsoon winds?
How does the differential heating of land and sea influence the behavior of monsoon winds?
- It only affects local wind patterns, with negligible influence on the broader monsoon wind dynamics.
- It causes a seasonal shift in wind direction due to variation in heating and cooling rates, resulting in winds blowing from land to sea in winter and from sea to land in summer. (correct)
- It results in a uniform distribution of temperature and pressure, leading to a static wind pattern with minimal seasonal changes.
- It leads to a consistent wind pattern where winds always blow from land to sea, maintaining a stable atmospheric condition.

Study Notes
- Cups always rotate in anti-clock direction.
- Two readings from anemometer are noted down at 3 minutes interval
- To get wind speed in km/hr, the difference between anemometer readings is multiplied by 20
Hopkin Bioclimatic Law:
- Crop production and specific morphological developments are delayed by four days for each 1º latitude, 5º longitude, and 12 m altitude as one move northward and upward, respectively.
Monsoon
- The word "monsoon" comes from the Arabic word 'mausim,' meaning season.
- Monsoon is the seasonal reversal of wind direction over the earth's surface due to the differential heating of land, oceans & earth rotation.
- Monsoon winds blow from cold to warm regions because cold air takes up more space than warm air.
- Monsoon winds blow from land to sea in winter and from sea to land in summer.
- Monsoon winds may be considered as sea breeze as the air over land warms faster and reaches high temperature or low pressure than the air over the sea, this forces the wind to blow from the sea (high pressure) over land (low pressure).
- Due to the movement of air from the polar region, pressure decreases at the polar region, known as polar calm.
- The latitudinal zone between 30 to 35° N and S, is called horse latitude.
S-W Monsoon
- Also known as summer monsoon and occurs from June to September.
- Brings about 75% of the annual rainfall in the country.
- Known as a grand period of rainfall.
- Divided into two parts: Arabian Sea Branch and Bay of Bengal Branch.
- Arabian Sea Branch first causes rainfall in the Western Ghats of the coastal area of Kerala.
- Therefore, Kerala is the first state of India to receive rainfall from S-W monsoon.
- The Arabian Sea branch moves northwards along the Western Ghats, west of Western Ghats (not in the east of Western Ghats).
- Bay of Bengal Branch flows over the Bay of Bengal towards northeast India and Bengal.
- Rainfall occurs in Eastern Himalayas after that the wind turns towards the west over Indo-Gangetic Plains.
- Both these branches occasionally clash near Delhi.
N-E Monsoon
- Also known as winter monsoon or retreating monsoon.
- Occurs from December to early March.
- Brings rainfall in J&K, TN and the South part of AP.
Western Disturbances
- From October to March.
- Enters India through Iran, Afghanistan, and Pakistan and moves eastward across northern India and Assam.
- Brings rains in N-W parts of the country.
- Locally known as Mhawat, which is beneficial for Rabi crops.
