Anticyclones are generally associated with dry & calm weather. An anti-cyclone is a large atmospheric circulation system with the wind flowing clockwise around it in the Northern Hemisphere, and counter-clockwise in the Southern Hemisphere. Anticyclones form from air masses cooling more than their surroundings, which causes the air to contract slightly making the air denser. Since dense air weighs more, the weight of the atmosphere overlying a location increases, causing increased surface air pressure. The air mass cooling that results in an anticyclone forming can be caused by either conduction as the air flows over a relatively cool ocean surface, or through the loss of infrared radiation over land during the fall, winter, or spring when little sunlight is available to warm the air mass.

All given statements are correct Growing of two or more than two crops simultaneously on the same piece of land is called inter-cropping. It yields higher productivity per unit area. It is mostly prevalent in plantation crops like coconut and areca nut. Main objectives of intercropping are:Insurance against total crop failure under aberrant weather conditions or pest epidemicsIncrease in total productivity per unit land areaJudicious utilization of resources such as land, labor and inputs
Withering is used to remove excess water from the leaves and allows a very slight amount of oxidation. The process is also important in promoting the breakdown of leaf proteins into free amino acids and increase the availability of freed caffeine, both which change the taste of the tea.
The high concentration of jute mills in the Hooghly basin are because of the presence of lot of water which is easily available from the Hugli River. Iron and coal also available from Raniganj mines. The suitable type of climate (24°C to 35°C temperature, rainfall of 120 to 150 cm, 80 to 90 % relative humidity ) is found in West Bengal.
