soonaami ka chitran, 19veen shati

samudra ke bheetar achaanak jab badi tej halachal hone lagti hai to usamein ufaan uthata hai jisse aisi lambi aur bahut oonchi laharon ka rela uthana shuroo ho jaata hai jo zabardast aaveg ke saath aage badhta hai, inheen laharon ke rele ko soonaami kehte hain. daraasal soonaami Japani shabd hai jo soo aur naami se mil kar bana hai soo ka arth hai samudra tat auऱ naami ka arth hai laharein. pehle soonaami ko samudra mein uthane vaale jvaar ke roop mein bhi liya jaata raha hai lekin aisa naheen hai. daraasal samudra mein laharein chaaaind sooraj aur grahon ke gurutvaakarshan ke prabhaav se uthati hain lekin soonaami laharein in aam laharon se alag hoti hain. 11/03/2011 ko bhi yahi hua

kaaran

Indonesia ke nikat soonaami laharon ka udgam

soonaami laharon ke peechhe vaise to kai kaaran hote hain lekin sabse jyaada asaradaar kaaran hai bhookamp. iske alaava jameen dhansane, jvaalaamukhi fatne, kisi tarah ka visfot hone aur kabhi-kabhi ulkaapaat ke asar se bhi soonaami laharein uthati hain.

bhookamp

jab kabhi bheeshan bhookamp ki vajah se samudra ki oopari parat achaanak khisak kar aage badh jaati hai to samudra apni samaantar sthiti mein oopar ki taraf badhne lagta hai. jo laharein us vakt banti hain vo soonaami laharein hoti hain. iska ek udaaharan ye ho sakta hai ki dharati ki oopari parat futabaul ki paraton ki tarah aapas mein judi hui hai ya kahein ki ek ande ki tarah se hai jismein daraarein hon. pehle soonaami ko samudra mein uthane vaale jvaar ke roop mein bhi liya jaata raha hai lekin aisa naheen hai. daraasal samudra mein lahare chaaaind sooraj aur grahon ke gurutvaakarshan ke prabhaav se uthati hain lekin soonaami laharein in aam laharon se alag hoti hain.

jaise ande ka khol sakht hota hai lekin uske bheetar ka padaarth lijlija aur geela hota hai. bhookamp ke asar se ye daraarein chaudi hokar andar ke padaarth mein itni halachal paida karti hain ki vo teji se oopar ki taraf ka rookh kar leta hai. dharati ki paratein bhi jab kisi bhi asar se chaudi hoti hain to vo khiskati hain jiske kaaran mahaadveep bante hain. to is tarah ye soonaami laharein banti hain. lekin ye bhi zaroori naheen ki har bhookamp se soonaami laharein bane. iske liye bhookamp ka kendra samudra ke andar ya uske aaspaas hona zaroori hai.

tat aagaman par prabhaav

jab ye sunaami laharein kisi bhi mahaadveep ki us parat ke uthale paani tak pahuainchati hain jahaaain se vo doosare mahaadveep se juda hai aur jo ki ek daraar ke roop mein dekha ja sakta hai. vahaaain soonaami lahar ki teji kam ho jaati hai. vo isliye kyon ki us jagah doosra mahaadveep bhi jud raha hai aur vahaan dharati ki judi hui parat ki vajah se daraar jaisi jo jagah hoti hai vo paani ko apne andar raasta deti hai. lekin uske baad bheetar ke paani ke saath mil kar jab soonaami kinaare ki taraf badhti hai to usame itni teji hoti hai ki vo 30 meter tak oopar uth sakti hai aur uske raaste mein chaahe ped, jungle ya imaaratein kuchh bhi aaeain- sabka safaaya kar sakti hai.

prabhaav

soonaami laharein samudri tat par bheeshan tareeke se hamla karti hain aur jaan-maal ka buri tarah nuksaan kar sakti hai. inki bhavishyavaani karna mushkil hai. jis tarah vaigyaanik bhookamp ke baare mein bhavishya vaani naheen kar sakte vaise hi soonaami ke baare mein bhi andaaja naheen laga sakte. lekin soonaami ke ab tak ke record ko dekhkar aur mahaadveepon ki sthiti ko dekhkar vaigyaanik kuchh andaaja laga sakte hain. dharati ki jo plets ya paratein jahaaain-jahaaain milti hai vahaaain ke aaspaas ke samudra mein soonaami ka khtara zyaada hota hai.

jaise Australiaee parat aur yooreshiyaai parat jahaaain milti hain vahaaain sthit hai sumaatra jo ki doosari taraf Philippinee parat se juda hua hai. soonaami laharon ka kahar vahaaain bhayankar roop mein dekha ja raha hai.
