rilling

Geography; Physical geography

A series of small channels which form on a slope after heavy rainfall. Each channel may only be a couple of metres wide and half a metre deep, but they can develop into gullies if rainfall events are ...

green movement

Geography; Physical geography

Non-governmental organizations, political parties and, increasingly, public opinion which propose that care for the environment should inform and mould our behaviour much more than it has ...

saturated adiabatic lapse rate

Geography; Physical geography

The rate of fall in air temperature by adiabatic change as saturated air gains altitude. Varies between 4 and 9蚓 per 1000m. Is slower than the dalr as latent heat is released during condensation.

tropical cyclone

Geography; Physical geography

A severe low pressure weather system which develops over tropical maritime areas. A steep pressure gradient and the central uplift draws in high speed winds which spiral towards the central area. ...

lapse rates

Geography; Physical geography

the rates at which air temperature decreases with altitude. Three types: Environmental lapse rate (elr) Dry adiabatic lapse rate (dalr) Saturated adiabatic lapse rate (salr)
