anukram
ritueain aur mausam
haalaanki aam janamat yeh hai ki ooshnakatibandh ek garm ilaaka jahaaain hamesha varsha hoti rahati hai aur hariyaali rahati hai lekin vaastavikta aisi naheen hai. yahaaain aise kai kshetr hain jahaaain par khushk aur nam mausam paae jaate hain. nam mausam tab hota hai jab us ilaake mein varsh ke ausat ki adhiktam varsha hoti hai.[2] isko paryatan ko badhaava dene ke liye harit ritu ka naam bhi diya jaata hai.[3] nam ilaake poore ooshn aur up-ooshn katibandh mein faile hue hain.[4] nam maheena vah hota hai jismein 60 mi.mi. ya adhik varsha ho.[5] ooshnakatibandheeya vanon mein khushk aur nam mausam naheen paaya jaata hai kyonki yahaaain poore saal bhar samaan roop se varsha hoti hai.[6] aamtaur par varsha ritu khushk garm mausam ke ant mein shuroo hoti hai. kuchh ilaakon mein to itni baarish ho jaati hai ki baadh aa jaati hai jisse mitti ka kataav hota hai aur mitti ki urvarata bhi ghatati hai. is kshetr ke adhikaansh jaanvaron ke liye yeh bahutaayat ka mausam hota hai aur unka prajanan kaal isi se sambaddh rahata hai.
beemaariyaaain
vishv ki sabse ghaatak beemaariyaaain bhi is kshetr mein bharpoor hoti hain. kyonki yahaaain ka vaataavaran machharon ke panapane ke liye bhi anukool hota hai isliye yahaaain machhar-sambandhi beemaariyaaain bhi bahut adhik hoti hain. kai beemaariyaaain to aur ilaakon mein pai hi naheen jaati hain.[7]
