On her way to school Tuesday morning, Ana got soaking wet during a surprise rainstorm. She was not carrying an umbrella or rain jacket because the climate in her town was normally very hot and dry. What are the main factors that influence the amount of precipitation in an area or region?

Prevailing winds

Presence of mountains

Seasonal winds.

Explanation:

Prevailing winds:

Prevailing winds is the wind that blows across an area or surface over time. It affects the amount of precipitation. If winds blows inland from water bodies such as oceans the amount do precipitation will be high because they carry more water vapor than the winds that blow over land.

Presence of mountains :

Mountain ranges affect precipitation too.The windward side of the mountain, which is the side the wind hits has higher precipitation while the land on the other side of the mountain, leeward side, will have little precipitation.

answer: semi-infinite solid initially at a uniform temperature of 400 ◦c is cooled at its surface by convection. the cooling fluid at a constant temperature of 200 ◦c has a convective coefficient (ha) of 250 w/m2.k. the physical properties of the solid: k = 20 w/m.k and α = 4 * 10-5  m2/s. using δx = 0.04 m and δt = 10 s. write the finite difference equations describing the transient heat transfer of the first five δx and the temperature profile after 30 s.
