Geography Doubts

Can anybody explain how cold core cyclone is developed ... As the center of cyclone has low pressure how can it be cold ? Plz help ..

i think it must b extra tropical/temperate cyclone which does not have eye and fronts often creates cold core....

Snow line is lower in eastern or western himalyas??anybody please clear the doubt

Snowline is lower in western himalayas
Coz of latitude altitude precipitation and other reasons

That is what is written in khullar that due to latitude snowline should be lower in western himalyas. But according to alok ranjan sir and majid hussain's book on geography of india: snowline is lower in eastern himalyas,as more the moisture in the atmosphere lower the snowline.So which one to go with?

What khullar has written is true only in principle . At or near the equator, the snowline is is typically situated at approximately 4,500 meters (or about 15,000 feet) above sea level. Beyond the Tropics the snow line becomes progressively lower as the latitude increases and the western Himalayas is at a higher latitude than the eastern Himalayas and both are beyond the tropics , but their is a catch here the relative location to the nearest coastline can influence the altitude of the snow line and the amount of precipitation. The western Himalayas is comparatively farther away from the coast and there is much less precipitation in the western Himalayas than eastern Himalayas so a lower snowline in Eastern Himalayas is a higher possibility than the western part .

@sidharth575 Thanks a lot. That clears the doubt.

North East trade winds flow towards equator then how can it help in turning north equator current away from equator in form of florida/gulf stream?

Whats the first stage of dtt....at places it is called high fluctuating(shabbir notes,random webpages) and sometimes referred to as high stationary(majid hussain)

@munchun The Gulf Stream, located along the eastern coast of the United States, beginning in the Caribbean and upto the northern North Atlantic is an important current plays an important role in the poleward transfer of heat and salt and serves to warm the Europe and North American land masses . The Gulf Stream begins upstream from Cape Hatteras but it actually starts from the mexican gulf where it is joined by the florida current which can be considered the "official" beginning of the Gulf Stream . The origin of the florida current is due to amassing of huge volumes of water in Gulf of Mexico due to the trade winds.

The above reason is the secondary cause the primary cause is due to North Atlantic Gyre located in the Atlantic Ocean I'm assuming you know about the five major gyres operating in our oceans and other smaller ones , anyhow the Gulf Stream , the North Atlantic Current , Canary Current and North Equatorial Current form the four arms of the gyre , now this gyre under the effect of NE trade winds and the westerlies above 30 N latitude rotate this gyre in clockwise direction which helps the Gulf stream move in that particular direction and obviously the shape of the coast . Always remember the western arm of any gyre is stronger than the eastern arm.



@azrimbilahg First stage of dtt is high Stationary Stage anyone saying otherwise is wrong.

1) Why himalaya is in sword like shape i mean it shoud have been reversed coz indian plate is pushing it towards north?
2) why himalaya does nt have volcano though its highly EARTHQUAKE sensetive zone, it is a big exception why is it so?
3)what is double equitrial trough(low pressure zone both sides of equator) why its get created which is prerequisite for monsoon burst?
