Why do differnt GCMs simulate a same variable differently?

My question might sound bit silly. But, I am really curious to know what makes two GCMs differnt? We know, GCMs simulate past and future climate based on some assumptions. Regarding future, we can...

How to calculate drainage density of a basin using Arc-GIS?

In theory clasees, we all have learnt about drainage density (DD), which is the ratio of 'total length of stream network in a basin (L)' to the 'basin area(A)'. However, when, we are trying to...

Why most of the RCMs provide data with a resolution of 0.44 degree latitude × 0.44 degree longitude?

When we download different hydroclimatic data from CORDEX, we can observe that most of the data are with a resolution of 0.44 degree latitude × 0.44 degree longitude. Is there any particular...

Hi! Can anyone suggest me some bias-correction procedure , using which I can debais extreme rainfall e.g. Annual max daily precipitation?

Actually, I am working on future aspects of precipitation extremes using different RCM outputs under different RCP scenarios. However, any model output possess significant bias w.r.t. the observed...

Hi! I am quite curious to know what is the differnce between hindcast data, historical simulated data, and reanalysis data?

While handling climate data, we come across those above-mentioned terms quite often. But, my concept is not much clear regarding this. Which kind of data do we get from GCM historical run?
