in connection with the-following effects: .(4) The bolometric effect

role. (4) Reating of the electron gas by irradiation (change of the
energy distribution of the conduction electrons): The emf signal observed.
in non-zero magnetic field "d v - 0 (which cannot be attributed to an
impurity photoeffect) is due to an electron-temperature gradient and can be'
considered as a kind of Ne.rhst-Etti4ibausen effect6' Semi quapt I tative

ABSTRACT: The author proposes a method for computing the advective
influx-of heat, based on the assumption that at a given
point within a small area the distribution of temperj,-!.,-
ture is represented by a surface of the second order.--'
The suggested technique makes it possible to reduce the

The prespnt work describes a possibility for the.removal of arbitrariness in
satisfying boundary conditions when solving the kinetic equations of BOLTZK M
and for the ascertaining of the rigorous solution by spherical harmonics. For
purposes of simplicity the isotropic soatteri'ng-of light in the atmosphere in
studied. The corresponding transport equation of the radiation energy and the
boundary conditions belonging to it are given. The albado of the surface of
the earth in assumed to be equal to taro, and from the surface of the upper
boundary of the stratosphere no radiation in assumed to be scattered to the
atmosphere. The solution of this transport equation is set up as a development
in series according to spherical harmonics. In view of the fact that in the
case investigated ecattering-is isotropict LEGENDREIS polynomials are inserted
into the transport equationt and the infinite system of equations for the
coefficients of the series is given. The solution of the shortened system of
equations for the coefficients of development is then an approximated solution
of the transport equation. If the index of the system moves from zero to Xt
the system of equations for the coefficients of development comprises N + I
differential equations of the first order.
'The solution of this system is here denoted by the vector J(,v) with the c.om-:

be determined from tho'boundary conditions. These boundary conditions and the
coefficients of development occurring therein are explicitly given.
According to the author's opiniony and in 'contradiction to what has been said
by S.CHANDRABEKHAR Ap.J.219 No 180 (1944) and other authors, there follow from
these boundary conditions exactly N+1 equations for the determination of the
V+1 arbitrary constants. When using the method of spherical harmonicat the
number N is beat employed as an odd number,' in which case the characteristic
equation of the matrix of the system of equations contains only even powers of
the unknown and therefore has (N+I)/2 positive and the same number of negative
solutions. If n is finite the characteristic values of the matrix are.not all
equal to 1/2 or -1/2t but with N -9@ 0 all"roots tend towards 1/2 or -1/2.
In conclusion-the system of.equation consisting of N+1 equations is given-for
the determination of the N + 1 arbitrary constants. By inserting these constants
into the expressions for the coefficients of development in the series accord-
.ing to LEGENDRE polynomials, the solution of the aforementioned transport
.equation is obtained. Finallyl a meth:od of improving this solution is described.

ABSTRACT: The.problem.of,radiation scattering in a plane-parallel
atmosphere with non-spherical scattering curve is formulated,
and the method of spherical functions is used for its
solution. The here applied method of spherical functions
has the advantage of utilising-the invariance of the
scattering relative to a turning of the coordinate system.
The problem of fulfilling the boundary conditions is
discussed. Formulae with a greater degree of exactness are
derived for determining the intensity of scattered radiation,
when the albedo of the'Earth's surface is taken into account.
Examples are given of calculating the intensity of scattered

The water vapour distribution is important in questions
of,atmos&erie heat balance, average air temperature at
different,heightsand places, and humidity (Ref.1).. At
present, full data'are only:available for Moscow (Refs.2,3)-
together with charts of the.absolute humidity distribution
for'two months-of the year - January and July (Ref.4) and
charts of the-relative humidity for each month (Ref.5)., In
view of this lack of information on density distribution, the
authors attempted to construct a chart giving variation with'
heightfor the whole of the Soviet Union and for all seasons.
of the year. In order to do this material from the Soienti-_

dovatel,Iskiy institut aeroklimatologia) on the mean seasonal
values of the relative humidity and temperature for 57
